[QUOTE="thudpucker, post: 304415, member: 1422"] Pappy's good! :) I have a little experience to go along with Pappy's logic. Take that Idle (low speed jet) out and look at the pointed end for damage. Some folks just cannot resist cruelly torquing those screws down which damages the point. When that happens, the flow across the point is disrupted. A tiny bit of turn can make a Huge difference in the fuel/air flow. What ever you do, DONT [-X mess with the seat the small point fits into. If that seat is messed up, you need a new needle & seat if you can get it. That Seat angle etc is specifically formed. Not something you can do by hand. [/QUOTE]
