Re: First MB Build. Help Needed.
half choke to start is normal.
as for the air filter set-up, you say you've got the black plastic circle and the sponge thing still on, but how?
did you cram the sponge into the carb and then bolt the circle on over it?
if that's the case, the sponge is probably blocking the air from getting into the carb, which would result in bogging and your motor dying. it would go slow, because it's not "breathing" properly.
and when you say you slow down and it dies, you are pulling the clutch in before stopping, right? these motors won't idle without the clutch (if you are, don't laugh. a lot of people think the clutch is just for starting it or rolling the bike when it's off.)
