Hi guys. I have a question from somebody who knows NOTHING about engines... ok here goes.
I have an old 1970's moped. It runs great, but when it's idling, the back wheel spins like crazy. For instance if it's on the center stand and the engine's running, the wheel is still turning really fast (without giving it gas) unless I hold the brake. This isn't really a problem, because if I'm sitting at an intersection or something, my weight keeps me from speeding off involuntarily (obviously).
Also, the acceleration is terrible on the thing. It takes a while to get going from an intersection or whatever. But when I do get going, it's great! 30 mph.
Anyway, somebody told me that what I should do is fine tune the carburator. Apparently there's two jets that can be adjusted with a screwdriver and can be set in a delicate balance to increase acceleration and allow the bike to idle properly.
Does anybody know what I'm talking about? Does this make sense? And if so, how would I find these jets to make the adjustments.
ANY help would be greatly appreciated!
Thanks in advance!
