EricJB Posted July 28, 2013 Report Share Posted July 28, 2013 Idle jets do more than just idle. That's what the air/fuel mixture screws are for. Idle jet are from idle to about 2200 to 2500 rpm, light to moderate throttle. The sputtering, and the air/ fuels being out so far tells me they need to be bigger. It cant hurt to try a bigger set. Then with it at idle, turn the air/ fuels in, one at a time, until the rpms start to drop. then out slowly till it comes back. They are like a faucet. In is lean, out is fat. you want the highest leanest idle setting. Good luck Quote Link to comment
