RE: what causes the engine to backfire or pop??
We managed to get it to work a little better, It runs really well, tons of power but the temps are pretty high, 330 [X(] but thats the only temp it will run more consistantly at. It still seems once and a while it sucks air, like when running out of fuel at about 1/4 tank or so, I'm guessing this is normal. Should he reseal the engine??? And what about the high temps??? If all this dont work I'm gonna guggest him to buy a new engine. What do you guys think??? After all this running today the compression and pinch is still there.
