I recently picked up a lightly used kart with a Vortex Rok GP engine that I’ve taken to two events. The karts worked fine the first event, but at the second event it had problems where it would start up and runs fine on the kart stand but as soon as it’s on the ground if I give it wide-open throttle it dies. Half throttle seems to work okay.
I’ve tried a new spark plug, took the carburetor apart and cleaned it with compressed air and carb cleaner (it was very clean already). The fuel filter looks clean as do the fuel lines.
Does anyone have any suggestions I can try?
My current guess is that it’s either an issue with the fuel lines or filter, or maybe because it dies only on the ground under full throttle it’s a problem with clutch engagement?
Thanks in advance for any help, I’m super new at this.
