Went from HP carb back to stock now its 4stroking pretty bad. Colder weather now also. Carb set with stock settings. Where should I put clip and should I put in a smaller jet? Thanks for the help.

you will have to play with jetting if your doing that but more than likely you can just screw in the the air/fuel screw all the way in and go out 2 full rotations then just listen to your engine and keep unscrewing to your liking
