I'm new to asking for help online and hope I'm doing it right. I have a Honda gx390 with a unknown brand replacement carb. Fresh rebuild on the motor and running on gas. I have added a k and n style filter and a long tube exhaust with a high flow atv muffler. I was wondering if anyone could tell me what size main jet and pilot jet and emulsion tube to use and where to get them. Right now kinda idles ok but having to screw the air screw out about 5-6 turns. Will not come off idel without popping and trying to die.
