ok fellas, i got the cub together and did a leakdown test, i lost 1psi in 6mins, is that acceptable? so now my left side pipe heats up almost instantly, gets hotter way b4 the right side. i switched coils, both have spark bc i got shocked on both sides. switched plugs also and still have the same outcome. i thought maybe it was my carbs but both are syncd pulling 4even on the tool, i even switched the carb on the cold side with another one and still got the same outcome. what else kud it be??
