Interesting... I used to have an old Quicksilver weightshift (with the 15hp Yamaha engine). It had a cap that was made to slip over the stud (not solid) terminal spark plug cap with the terminal removed; there was a spring loaded metal ball that pressed on the threads. This would seem to be a good solution; no worries about obtaining solid cap plugs locally, and no worries about the screw on cap coming loose since you already removed it. Confused the hell out of me at first, though. Apparently that's the "F" instead of "E" in the part number. BTW, all this talk of resistor plugs... my understanding was always that if you have a resistor cap you should NOT also use resistor plugs. Als, that LB50EZ part number... are you sure it's correct? That NGK page shows "05" but not "50". -Dana -- -- 1. Misogynist.........Women are no good 2. Feminist...........Men are no good 3. Environmentalist...People are no good 4.

I received suggestions that I get a rf capacitor to stop it. I was unable to do so without going on line and ordering one. I generally have a bit of trouble buying something that I can't examine. ( we all have our quirks) One of the problems that I had with an earlier version capacitor was that it screwed with my RPM's on my EIS. So I called the gal at EIS and asked her about the problem. She told me to change to the gray wire out of the rectifier, but that it would cost me the check for one of my mags. She mentioned a RF choke from Radio Shack that should do the job of cutting out the static interference. The numbers are 273-105 and 273-104. Look them up on the Radio Shack web page. Most all the Radio Shack stores carry them unlike the capacitor. The cost for both is under $15.00. They work by wrapping the wire around one of the chokes and the other works by just passing the wire through it. In a conversation with Roger Hankins, I found that the choke will eliminate the necessity of matching your RG cable length to the antenna. I cannot tell you any more about this aspect, perhaps Roger can clarify that. The weather finally moderated enough to allow me to fly today, so off into the wild blue I went with the wife giving me radio checks on the ground. I am pleased to report that there was "minimal" static with the use of these, and it APPEARS that the distance has been increased dramatically. I caped appears, since there has been no exhaustive testing done. The only thing that I can tell you is that before the chokes I could only talk to her from about 8 miles. This time there was no noticeable difference in quality at that distance. Good enough for me, you can make your own deductions. I did have to remove the power wire to the 196 gps though. My choke is placed on the main feed wire from the battery to the main power bar. All the power originates there through the master switch. The GPS power wire makes a static build up that culminates in a "pop", then builds again. Karen can't hear it, but it is quite loud in my head phones. I will wrap the power wire around a choke and see if that helps. If not then I guess I am going to have to buy some stock in Delco batteries.

I am not concerned about having lugs or not where it bolts down to the 912's, those bolts are huge, and the diameter of the pattern is large, meaning the will be lightly stressed. I have one of the RED extensions you posted in some of your pictures. I have two concerns about this, first is the taper in the extension itself down to 2 inches before the flange to attach it to the prop. Second, using the smaller bolt pattern on the warp puts a LOT more stress on the small bolts that attach the prop to the spacer itself, these bolts are pretty small and do break sometimes. The stress on those bolts increases almost exponentially as the bolt pattern diameter gets smaller. Its just plain dumb using the smaller pattern when the larger one could be used. Attached is a picture of my spacer... I like two things about your hub, first is has no super thin taper in it sressing the aluminum neck itself. Second is the larger bolt pattern on the prop side takes a lot of load off the thin prop bolts. ( I also like the cool black color :) it matches my prop ). One thing I have to ask though is why use 6061 aluminum instead of 7075 ? Isnt 7075 a lot stronger ? If memory serves me right, isnt the red spacer made out of 7075 ?

I do it because the spring was there when I bought the plane.

This is all the ground your antenna needs. If you have a second ground from the antenna to the frame you create a ground loop through which all sorts of noise can enter. I found a rat's nest of wire in my mk 3, quite a bit of which was going from the battery, alternator, and various filters to the MicroAir 760 radio. The real problem was that included in the nice big ground plane she had under the antenna mast was a nice fat wire going from said ground plane to ships electrical ground. Once I got rid of that extra ground strap the filters on the alternator and battery (don't ask me, maybe the more is better approach) came off and the noise was quiet.

Hankins" When tuning my Firestar antenna I reached a point when trimming the antenna length didn't improve the SWR. The reading was still a 2.7; not horrible, but I wanted better. I spent an evening or two reading all of the HAM sites about antennas and discovered that one can either match the length of the feed co-ax to the frequency just as one does the antenna, or install a choke or balun to "divorce" the feed line from the antenna. I didn't have any ferrite napkin rings around so I trimmed my coax 7" (I got the theoretical magic length from an online antenna calculator a HAM guy put up on his site). I now have an SWR of 1.6. The co-ax trim made more difference than the antenna trim did. I'm no radio expert, I just know it worked for me. I did read enough to get the impression that antenna design is truly a black art. Here is a link to one of the sites I saved in my favorites. http://www.electronics-tutorials.com/antennas/antennas.htm If you want to know about antenna stuff, Ask a HAM! -------- Roger in Oregon 1992 KXP 503 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=99198#99198 ________________________________ Message 22 ____________________________________ Time: 11:19:37 PM PST US Subject: Kolb-List: Re: carburetor rebuild schedule From: "The BaronVonEvil" Hi John, As for carburetor maintainence I usually check my carb in the spring just before the flying season gets going. I drop the float bowl and check for dirt & muck. It seems no matter how many or how fine a filter you have, dirt some how manages to get through. I'll check the jets for build-up of funk and make sure the're clean & secure. Next check the throttle sleeve, bore and jet needle for condition and wear. Then its the throttle cable, enrichener cable (if used) and fuel lines & fittings. Also check the carburetor to manifold rubber coupler for attachment, flexability and cracks. Finally, I will inspect and clean the airfilter and re-oil it with the filter manufacturer's oil. Usually, if the plane is being used regularly, fresh fuel is being used, the carb(s) should provide accurate and reliable service. Nevertheless, vibration, the fuel itself and UV light will take its toll of the carburetor and its related parts. It really doesnt take very long to do this work, maybe a half hour for each carburetor. If you havent done any work on your carburetors I'd say you really need to check them throughly before heading off into the wild blue yonder.
