I have to believe it's ignition related, if it were way lean you would have stuck it first. I would expect to see a hole or some sort of melted piston inline with the spark plug hole. The only other thing I can think of, like Chuck was saying about the big end rod bearing, is that if it were was loose enough, it might on the upstroke over extend and tighten the squish enough to make the motor deto, real bad!!! You should be able to stuff a screw driver in the spark plug hole and rotate the motor back and forth to get an idea of how loose the left rod is compared to the right. Just be CAREFUL!!!! The only 3 things that I know of that would melt a plug, ignion problem, detonation, or bad plug. Does anybody know if Q will work on a 440?

I've seen too hot, where lectrode and ground are melted, and I've seen the most recent where they look to be welded together at the tips but with no rela indication of disfiguration due to lack of clearance. > > The jet size sounds right.

A cable affair that reach downintot he carb area. I will most definitely move the CD and coil into the air stream. Good idea. > Is your engine hard starting and will not seem to idle smoothly ? The car has never been hard to start and it runs quite nicley at idle. It isn't till the car has been run with enthusiasm for 10 min or so that it starts running raggedy and finally stops running on the left cylinder. That ultimately brings the other side down.
