This is just a guess from your post that I'm able to decipher, sounds like a timing issue to me.

I just answered a PM.
It sounds lean if anything.
Start by posting what size jets are in the carb, and let's go from there.
It could also be an air leak in the cases, or intake tract.

Are you running an air box or a "pod" type filter?
