I know it lightens the crank but if the crank was designed to be filled (according to the pictures), and is not, doesn't that mess up the fuel volume?
30% Maxy Fuel
Have tried both a Novarossi 6 cold and hot
A copper shim added.
If I lean it out at all, I start getting temps of close to 300 degrees and the engine starts sounding like it's starving for fuel.
I run other engines without problems (Rossi R12, Mugen MT12, etc.) But this is my first higly modified engine.
