Any advice appreciated on setting up the carbs on the earlier model jinlun 125 11. Bike is running far too rich and yet will only run on choke. No choke it just stalls. Turning up the throttle stop is fine when engines warm but when next started from cold, the revs just race away and you have to back off the throttle stop again.....no choke - no idle. Plus choke is very hard to set, revs like mad or stalls with almost no in-between.
