Was wondering if alcohol motors show a burn pattern on the pistons like gas motors due?? This is on a 410 injected sprint motor.
Thanks alot Josh K.

pretty much. but the pattern is what it is. its a good way to see whats going on inside there at critical times. they should also have the same basic pattern on all of them.. obviously.
who built the engine ?? and what heads are on it?

one motor is a don ott the other is a gaerte. Both motors have 12* heads. Reason im asking is, pistons have only a little bit of carbon on them, all about the same though. I just wasn't sure if alcohol motors show a carbon burn pattern or not.
Thanks Josh K.

Alcohol has a tendancy to wash the combustion chambers clean, especially if they are rich.
