370bansheeSOFLO Posted January 9, 2019 Author Report Share Posted January 9, 2019 Leak test? Swap plugs? If you've swapped sides with the carbs, plug wires and reeds none of those are your problem. That also eliminates stator, cdi, coil, wire harness. Problem has to be a leak, a blockage in the pipe/silencer or something fubar in the cylinder itself.why kind of leak do you speak of? ill take the stinger off and see what happens. when i did the compression test it was 117psi and held strong.

Compression testers have check valves in them, tells you nothing about if the cylinder/intake is air tight. An air leak could lean the cylinder out enough to do what you describe. Masking it with jetting it richer will make it worse. Swap (or replace) plugs, blow through pipes and silencers and do a leak down test.
