Quick 2 stroke jetting question

Recommended Posts

Just rebuilt my CRM 250 and have a jetting question

Trying to get the needle position right. Mid throttle is really choppy and rough.Cuts out a bit initially. Runs perfect cold for the first 30 seconds to a minute without choke. When I let off throttle without clutch nothing happens. no engine activity(noise) if that makes sense. does that sound rich or lean . Im sure I need to tidy up the pilot curcuit a bit also. Main jet was fine before so Im assuming I wont have much to play with there. Maybe Im wrong.

Thanks a bunch, first time messing with 2 stroke jetting.
