I've got GM Harmuth's old Red Devil. I have yet to get a full event running
with it. It has been to a professional engine builder who is known around
North America for the engines he builds for drag racing snow mobiles. He
knows his stuff. Problem is, it will run great for a while especially when
cold, but then it just dies.
Today was the same as usual. My son and I went to the local autox. We both
got 4 runs of roughly seventy secs. Throughout this time, I pulled the plugs
twice, and each time they looked beautiful with a nice clean, dry, brownish
burn. The car ran good and felt strong then suddenly it stopped running on
one cylinder. We limped the car into the pit area and pulled the plugs, and
found the tip literally fused to the ground; it looked like it was welded.
This cylinder has been the source of trouble from the get go in April. I've
changed heads on it twice. I've tried different jetting and different heat
range plugs. Now I don't know what to do. I have no idea what sort of
intermittent problem will cause this.
