actually a snowmobile but i think you could help. really cold here lately, sled is a bit hard starting. occassionaly when engaging the throttle or stopping, it dies. starts back up and idles smooth. just a stalling and a little backfire...think my carb is dirty/icy?
i hate 2cycles! My race kart engines were always a major fucking pain. They like to run one way only--wide open. Unfort. u prob need to take apart and clean but try easy shit first.
