Starts and idles perfect , I've changed out pretty much everything major, fuel pump filter plugs ect ect running on both cylinders and the parking brake isn't pulled, I've had about a year long problem that I can't seem to fix, need some help. The machine starts up and idles perfect, it stalls out in high at 5mph and in low at 2 mph , bounces off rev limiter I'm neutral, desperately hoping someone sees this that has had this problem so I can fix it finally lol
