List, I haven't had much time to work on the #1 cylinder problem. I did manage to remove the spark plug wire . That wasn't easy, and putting it back was worse. The wire checks good. It is 452 ohms and 16" long , made from Taylor 8mm silicon @350 ohms per foot. I have a dc power supply that goes up to 32 volts. It showed 70 ma current when hooked up tp the supply. I twisted and pulled it as hard as I could and the current remained the same. So, the wire seems to be good unless it breaks down at high voltage. I'm going to look at it tonight in the dark to see if I can see any stray sparks flying around. I am wondering if I can do a compression check using the injector port? My compression gauge has a 45 degree bend in it and I wouldn't be able to get it in the spark plug hole. And yes , the plug carbons up , it does NOT get fuel nor does it get oil on it. I will keep you posted when I have the time to work on it some more. Thanks to all that have answered so far!
