HI there, I would be looking first at your idle mixture screws at the base plate. See how many turns it takes to seat them gently. Then turn 2 complete turns out, and see if that changes it. Make sure to note how many turns in it took to get them to seat and post back. Allthebest, c4c5 | ||||||||||||||||||||
