    Hi everybody, can you help me fix my speedfight 100. If I start the scoot every day or every other day it fires up first touch of the button, but if left for longer than that it will not start without taking the spark plug out & pouring a little fuel in the cylinder. It will then start & keep running no prob. Also it bogs down when I set off on it but when I get going a bit it goes like a good un until I ease off the throttle then when you throttle up the same thing happens for a couple of secs then it's off at a good pace again.

    Hi there, as far as I know the engine is standard although it has a sports exhaust & cone air filter on it so I fitted a larger main jet. It had a leak on the oil feed pipe so I am running it on pre-mixed fuel at the minute.
