i had a new powerpack and heat sensor installed last fall and it seamed to solve the problem, then right out of the gate this year it started. runs great, turn it off fish, start it up and it will not go over 4000rpms. some times it runs like crap at an idle then it goes great when you hit it and it will just drop a cylinder or more when running.on and off runs great -craps out anywhere anytime. pulled the plugs and found clean spots on some of the cylinders. i am wondering if this could be from a water leak in the head gasket?
the heads were milled and heli coils were installed, fuel appears to be leaking around the plug threads, could it be a compression issue? two of the plugs came out clean and dry , the other 4 were shiny/wet.
