Re: A lean condition

lean is good. lean makes power. Excess fuel (more fuel than there is oxygen to burn) cools... those pistons in the sled could have used some of that. Top fuelers spit 10' flames because too much fuel is the only cooling system they have.

Carbs are rotten, and because of that they are always jetted rich. That way the lean spots aren't so lean they melt pistons/.
EFI is better. That's why a modern V8 can put out 400 Hp and still get nearly 30mpg. They run lean. "Almost" to the point of pain lean. But not quite.

Ever run a lawnmower out of gas? Just before she quites, the rpm's go to the moon.
