Bill, You can buy a Fram 4967 at any local superstore; I've used them on Pete's recommendation since engine was new - over 240 hours ago. On that oil pressure...the Jab manual has normal operating limits of 31 psi minimum and 76 psi maximum. You better do some checkin'; start with the sender as many owners have had to replace the original unit. Also, under the filter donut you will find a circlip. Remove that and the relief valve and spring under it and check for debris. Occasionally the sealants used to button-up the engine might find their way to that location. An easy check the next time the filter is off - and peace of mind to boot. Andy at Suncoast will answer these questions far more reliably than we can. If you're in Georgia I assume you bought it from him??? tailwinds jeff ________________________________ Message 2 _____________________________________ Time: 01:04:06 AM PST US Subject: RE: Zenith-List: Cortec precautions are few From: --> Zenith-List message posted by: Jeff, Cortec 373 is not a particularly dangerous stuff. You will not get dizzy, brain damaged or loose your eysight, nor will you get cancer. But do not drink it or let it get into the eye. Immediately rinse with water if this happens. After using Cortec clean your hands with soap and water, and do not let it dry on clothing if you want to remove stains. Enviromentally it doesnt need special treatment either. The full 373 specs and health and environmental fact sheets can be downloaded from the Cortec site. So, no respirator is needed and gloves only to keep your hands clean. Use water for cleanup and alcohol to dilute the stuff and use a solvent only if you are totally dissatisfied and want to do an area completely over. When used as the primary aluminum primer, clean and degrease really well, to make it stick hard. Otherwise it will still give full protection, but scratches off. rgrds, Max 701 builder using Cortec in Helsinki RE > Subject: Zenith-List: Cortec precautions? > --> Zenith-List message posted by: "Jeff Davidson" > -clip- > I'm about to use the Cortec for the first time as I get ready > to final rivet the rest of my airframe.

All types of low-key fly-in fun in the beautiful mountains of central Pennsylvania. The J-2 Cub is the featured Piper aircraft this year so you might spot some oldies. Go to www.sentimentaljourneyfly-in.com for details and to download arrival procedures. The PA Bureau of Aviation is getting antsy about simultaneous operations on the paved and turf strip so you don't want to foul things up. Even though NORAD a/c are highly urged to have some form of comm with them, you might run into a/c in the area or pattern who are not in comm with the rest. Wayne Beattie always seems to be able to find a break in the clouds and get through; I'll be there if wx allows.

Goodings" Subject: Zenith-List: Re: Zenith-List Digest: Cutting aluminum --> Zenith-List message posted by: "John M. Goodings" By and large, I don't like shears/snips. I made a wooden handle for a 10-inch hack saw blade. With this, I can cut right up to the line without any distortion of the Al sheet near the edge. It is easy to work near the middle of a big sheet, or cut right across a big sheet. At first, there is a tendency to have the blade flex sideways; one soon learns to control it. The blades are cheap to replace. Coarse ones (18 teeth per inch) are better than fine ones (say 32 teeth per inch). After that, a body file is essential, to my mind; it takes metal off fast. After that, sandpaper on a wood block - nothing fancy. Perhaps my favourite tool is a 12-inch aluminum oxide sanding disc (50 or 80 grit) glued to a 3/4-inch plywood disc, run by an electric motor (mine happens to be an old wood lathe) with a 15 x 8 inch plywood table at right angles to the disc along a diameter; I used 2 Al oxide discs for the whole aircraft. If more than 1/8 inch of Al needs to come off, use a hack saw, not the disc (to save the disc). One can perform on Al like a surgeon with this!

This leads to much higher combustion pressures, crank wear and higher cylinder head temps (and burnt valves). Retarding the timing delays the whole process so at least it happens nearer the best crank angle (peak cylinder pressure at about 16 deg AFTER TDC and as the piston has moved further down the bore will reduce the pressure and hence the tendency to detonate. Hot spots tend to preignite the charge....very nasty for the engine, but because the detonation thing should be better with the ignition timing retard this will also decrease the combustion chamber temp and hance decrease the likelyhood of glowing hot spots.

I have been tinkering with automobiles for many years -no expert mind you - but many times I have had to fiddle with the timing to eliminate the run-on problem. An engine will "knock" at high power settings such as climbing a hill if the timing is advanced too much also.

This way I can work on it on a bench instead of upside down and it will be a lot easier to take it on and off to file the notches for the studs. Has anyone else done this? Am I missing something?

That ain't the problem. I would have to see the problem to fix but I would guess it is something real simple. Start with the basics, do a tune up, plugs, wires, etc. If you are running a carb or carbs, then you might try cleaning them out a little. Needle might have a tiny bit of trash under it. Make sure your idle is a low as it will still run. Let it idle for a few seconds before cutting turning off the key.

It does not happen when parked, only after flying. Looking at the carb opening it is clean if I remove the filter right after flying. No evidence of fuel coming out of the carb throat into the filter. I do notice a small orifice below the carb throat opening that looks to be stained. Could it be possible that there is fuel being squirted out of that hole into the air filter when the engine is running? I am using the K&N large round filter and I do not have the fuel overflow tubes stuck into the filter. What could cause this thick fluid to collect in the filter when the engine is running? (It is not the oil used to treat the filter element). Wayne
