I'm new here, I've searched the jetting but not really finding what I'm looking for, everything is stock besides quickshot and after market fuel screw . it cuts out soon as you come off idle and back fires about mid range. I'm about 1,233ft above sea level

You probably have a partly clogged pilot jet causing the problem.  http://www.thumperta...o/#entry6879695
