Make sure it is fully closing. Enjoy your flight! Gary Boothe NX308MB From: owner-pietenpol-list-server@matronics.com [mailto:owner-pietenpol-list-server@matronics.com] On Behalf Of Oscar Zuniga Sent: Saturday, March 15, 2014 8:00 PM Subject: Pietenpol-List: a day at the hangar So there were no more excuses left today. I finished installing the centersection flop with the new hinge, then installed the new pilot's windscreen, serviced the air filter- and there was nothing left to do. Dragged Scout from my hangar to the self-service pumps (which seemed like it must have been 20 miles, uphill), put 10 gallons in the tank, and towed the airplane back to the hangar. The tailwheel dolly makes it about as easy as it can be, but it was a good workout anyway. Tailwheel tied down, stick tied back, sumped the gascolator- and there were just no more delay tactics left to try. Mags off, pulled it through 8 blades with the throttle cracked, then made the mags hot and took off my outer shirt since I expected to get a good workout. The engine surprised me by lighting off on the third pull! Oil pressure came right up and everything looked good, so I put on my jacket and settled into the cockpit to give the oil a good warmup so I could change it after a year and a half of sitting. The ground shook as the thunder of the mighty A75 let the whole world hear its mighty roaring echoes down the row of hangars. Got the engine good and warm (oil temp about 170-175F), which took about 15 minutes at throttle settings from 1500 on up to full static RPM, and during that time I checked mag drops, carb heat, and just listened to the engine and felt it run. It's wanting me to keep carb heat on all the time and it actually gives an RPM increase, not decrease, and smoother running with it on. Mag drop was rough at lower RPM but cleared up as I kept inching the power up and up and letting the engine warm up. By the time I was ready to shut down, it still didn't like higher power settings without carb heat but it would run at 1500 as smooth as silk with the tach needle frozen in place and no carb heat. It also idled just fine, on down to about 800 RPM, no carb heat. I'll have to figure that out. Drained and changed the oil, noticed that my front main oil seal is still seeping enough to make me want to go ahead and change the seal, and then I put the airplane away. Next time out of the hangar, which could be tomorrow, we're going flying.

In Enid, OK there was a great little true value hardware store. Biggars. It had small boxes of screws and such and you could buy 5 #4 screws as well. they always had that little obscure part you needed or would get it. They were put out of business by Walmart and Lowes. (Notice almost every time you see a Lowes it is near Walmart.) Of course Lowes, only sells little nuts and bolts in packages of 5. They also don't carry anything that does not have volume sales so you can't find the part you really need. Yesterday I bought 4 #4 plastic washers for 56 cents. They are worth about 5 for a penny.

Commiserations on needing to do Prop seal. I have had to do it and in truth two things to say. Buying two Seals - great! As you can guess you'll only need one and all will go well. I think I took Prop off just to give a bit more space. I also worked from above the flange on a step of some sorts. The spring inside the seal I adjusted the 'hook' ends, compressed them so it readily coupled and stayed together when pushed into seal. The last action involved carefully prising seal over crank into recess ensuring it was lubricated. In truth it was a lot less traumatic than I envisaged. It will be fine.

I had such a leak when I built my A65, and it caused rough running and backfiring at idle. Check all those hose clamps and make sure all the rubber boots are on cleanly. As for the crankshaft seal, this is an easy task if you have a tapered shaft engine. More difficult with a flanged shaft. Good Luck!

I clean it periodically andt hen spray on some K&N filter oil, and maybe that's the problem. Ialso thought about why it may be running lean and one of the obviouspossib ilities is an air leak either at the carb base gasket or on one ofthe many intake spider clamps and fittings. I may need to check all ofthose out, to o. Withoutcarb heat on takeoff, the engine will stumble when power is applied, and ifcarb heat is not pulled immediately, the engine will die.

I am not sure if Bob, who you borrowed the mount from is on this list, but he sent us an exact width to make it to, so it would fit his plane like a glove. On the other end of the scale, we made one in the same fixture for Terry Hand's steel tube fuselage that was .750" narrower. We have spacers to put in the fixture to bias the mount point to fit either way builders measured their plane. If you chose to build it to Bob's with, let me know and I will make your mount accordingly.

The airplane starts wonderfully and predictably now, and I had no trouble starting it, cold or hot. Still no joy on resolving the carb heat issue though. I removed the air filter and ran the engine... no change whatsoever. Cross that off the list. I removed all four intake tubes from the spiders, including the clamps and hose fittings, and inspected everything. Nothing cracked, nothing brittle, nothing suspect- so I reassembled all the intake tubes and snugged down all the clamps and ran the engine again. Still no change; cross that off the list. Oh yeah, and I had asked somebody (Gary) about adjusting the idle mixture. The engine speeds up just as it quits when the fuel shutoff is pulled and the engine is allowed to run out of fuel, so I think the idle mixture is correct. My A&P friend had suggested checking the mixture control disks in the Stromberg carb, since they can sometimes get cocked when not assembled properly and they can allow air to go around the plates rather than through the metering holes. Unwired the mixture lever, pulled the mixture assembly cover and disks, cleaned and inspected, reassembled and re-safetied. Ran the engine again... no change. We're eliminating possibilities right and left. The next suspect is the diverter butterfly in the carb heat box. There is a slight gap between the edge of the butterfly and the body of the box, and there is a possibility that at higher airflows and engine speeds, the air is taken partially through the filter and partially through the hot air bypass and sets up a swirl or confused airflow into the carb. I'm going to adjust the butterfly and the carb heat actuation lever to make sure that the butterfly seals tightly when the carb heat is off. Next weekend ;o) I did get to taxi the airplane a bit with the new tailwheel and found that the Matco has its pros and cons over the Scott 2000. When the Matco goes into free castoring, which it does readily, I can pivot the airplane effortlessly on one main and maneuver it in very sharp turns. The downside is that it takes brakes and rudder to get it back into steering mode, a conscious effort compared to the Scott, which could almost read my mind. Some people have said that they leave a little slack in the tailwheel springs and cables and this helps, but I'll have to operate the airplane a little more as-is to see if I want to add slack. I don't like the idea too much. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=420445#420445 ________________________________ Message 33 ____________________________________ Time: 08:35:00 PM PST US Subject: Pietenpol-List: Re: leaking Continental front main seal From: "taildrags" The seal on my engine is essentially new, and has seeped oil since new because the crank surface was not prepared properly. I know what needs to be done and will do it, and I'm sure it will be quick and painless. Here's what my A&P told me is the way he does it: "If you have a microwave at the hangar, I pull the spring out of the seal and hook the spring back together behind the flange. Then I submerge the seal in a cup of water and microwave for 30 second intervals until it is steaming. Then just stretch it over the flange and let it shrink back up. While it's shrinking, work the spring into place in the back of the seal. Give it a coat of Permatex Ultra around the outside and in the seal cavity, and slide it into place. Make sure it's fully seated so the seal sits even on the crank and let it cure overnight." -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=420446#420446 ________________________________ Message 34 ____________________________________ Time: 09:02:03 PM PST US Subject: Pietenpol-List: Re: running lean From: "William Wynne" Oscar, An induction leak, like a hose, will mess up the idle, but it will have little or no effect on running the engine near it's full static rpm. If you engine needs carb heat to run at static rpm, something else is wrong. Plane sat for 18 Months? What kind of gas/was is in it? Ethanol or not, car gas with 1.5 birthdays is bad. If it was left in the carb, it possibly made things unhappy. Dirty idle circuit; again affects at low speed, but not near static rpm. You mention mag drop at idle? Traditionally, I use 1700 rpm to test the drop on a small Continental. Is it within limits at that rpm? Back to basics: It is likely the last thing you touched, and not very likely to be something like the leaning function in the Stromberg suddenly deciding that this was the moment to go out of wack. Mags off: Does the engine have normal compression on all cylinders? Do you have impulse on both mags? Are they 'clicking' at the same time? Pop the fuel line off right at the carb and make sure you can fill a 1 quart container in 65-75 seconds or less. Not likely to be the air box itself. I have seen engines run perfectly fine with airboxes that had the shaft holes walled out to 1/2". K&N filter oil is great for......K&N filters. not all elements like it. Spray it on some Bracket filters and you might as well have sprayed it with clear paint. -ww.

To address them one by one: The fuel in the tank was 100LL, but it wasn't there for long. Some time ago I drained the tank to replace the fuel shutoff valve. Nothing on that end of the system is a problem. Same with the carb... I pulled the small screen on the float bowl, cleaned it, and 'tickled' the float to make sure it wasn't hanging up on its pivots (it wasn't). Everything clicked and tinkled inside the float bowl just like it's supposed to and there was no sign of varnish or residue on anything. Mag drop at 1700 RPM is indeed where I test it on runup, and it is normal... about 50 RPM difference between drop on L and R mags. Mags are almost new Slicks, both have impulse couplers. I have not checked compression on the cylinders but will do so very soon. I have also not timed the flow from the fuel system to the carb, but can easily do that as well. My guess is that I can fill a quart container in less than a minute, yes... but will verify. I will ditch the K&N filter oil, clean my Air Maze filter again, and replace it- but I worried about the dust we had in Texas and wanted to have something that would hang onto the dust on the way through the filter. Up here in Oregon, we don't have much dust. In any case, I tried running the engine without the filter and it made no difference in the "I gotta have carb heat!" behavior. -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power Read this topic online here: http://forums.matronics.com/viewtopic.php?p=420448#420448 ________________________________ Message 36 ____________________________________ Time: 10:29:36 PM PST US Subject: Pietenpol-List: Re: Speaking of Doc... From: "William Wynne" Doc story #2; It's 1990 or so. I am working on becoming an A&P at Embry-Riddle to go with an Aero-engineering degree. I actually like the A&P skills better, as engineering education is being polluted by an invasion of computer science and programing. About 1/2 way through my Airframe license the FAA announces that they are going to have the "Charles Taylor Award" for outstanding A&P mechanic in the US. Great, adds to the esprit de corps, maybe something to shoot for in 25 years...... Month or two later, here comes a press release from the Feds: They decided that you need to have 50 years of being an A&P to even apply for the award. Great, I figure no rush on my application, I can't submit it until 2041. The bottom of the press release includes the name of some old guy they awarded the first one to, some cat named Donald Moster or Mostel or something....... Fast forward to 2004. I am visiting Doc' and Dee's place in Wisconsin. I have known them for a bit, Doc has even attended our first Corvair College. He has built his own Corvair engine at the following college. He seems like a promising student, I try and share a lot of my wisdom with him. When I am speaking with him, he often has a very interested look on his face and says things like "So that's how engines work! " It is my first visit to Doc's house. He is sitting at the kitchen table reading the editorial page of the paper and commenting on the wisdom of people who write letters to the editor. I am examining the pictures on the walls in Doc's office. I am stunned. It is a collection of been there done that, history of aviation classics. I am having the uncomfortable and rude awakening, that Doc has been playing "New guy" when he actually has an incredible depth of experience. Looking though the framed 8x10s I find a certificate with the department of transportation logo, leaning against a book, kind of dusty. It says CHARLES TAYLOR AWARD.....DONALD MOSHER. I clutch it in my hands and realize several things in rapid order 1) Donald moster or mostel = DONALD 'DOC' MOSHER......2) Doc knows more about engines than I ever will......3) I have spent the last three years speaking to him as if I had something to show him. I walk out to the kitchen, where Doc is still reading letters to the editor. He does not look up from the paper. Me: "You have THE CHARLES TAYLOR AWARD!" Doc: "Whatever...." Me: "You have THE CHARLES TAYLOR AWARD!" Doc: "Is there some point?" Me: "You let me speak to you like I was smart.....and You have THE CHARLES TAYLOR AWARD!" Doc, without looking up from paper "So what, it's all political, who you know, they hand them out like crackerjack prizes." Me: "My ass they do. 50 Years just to apply for it! I would cut off my left arm for this. I would sell my sister into the valley of the lepers, I would ....I would..." Doc, looking up from paper for the first time: "Really, Your quest for external validation isn't very becoming. You should look inside yourself for happiness and satisfaction. " Me: "Thanks, Obi-Wan Kenobi. I feel soooo much better. " -ww.
