Bill, The fuel filter is atleast an inch from the anything, and even futher from metal, so I know thats ok. The ignition cable sheathing is not frayed anywhere, The pictures are apparently misleading. I did however cover the entire length of ignition wire and pick up wire in thick walled rubber tubing. Not sure if the pickup wire contributes to any of the interferance, but I guess better to be safe than sorry. I have installed a rubber grommet for the Ignition unit power wire where it goes throught the Fire wall. While working on this thing, I realized that the Ignition wire runs VERY close to my throttle servo(mounted on bottom of the standoff) and pushrod. Unfortunately, this is the only way I can route the Ignition wire to the plug, so I am in the process of moving the servos (choke also) to the inside of the plane. I happened accross some good pictures of MVVS 1.60 linkage setups using bellcranks that seem to work much better than what I have. (I tried a bellcrank system, but after staring at it for a couple hours I gave up on trying to get it to function properly and settled for the current set-up).

I am going to mount the ignition battery on the opposite end of the cockpit area to get it as far away as possible, I will try all of this and ground check the crap out of it with my PPM receiver until I am satified that there is no more glitches. Afterwards, I will probably switch to a PCM, once my wallet gets over the sting of my latest purchase.... A New Funtana... PCM Receivers are EXPENSIVE....but then so are planes....so...

P.S. Dually noted about the fuel filter hose clamps.... I have some I can install. I will keep everyone informed once I am satisfied the problem has gone away.
