Hey folks I’ve been away from Karting for several years and decided to get back in it. Our local track offers a gas pro class (stock appearing).
I have put together a 212 with cam, oversized valves, ported head, arc rod, arc flywheel with 32 degrees advanced timing, big pipe and gx390 carb.
having issues figuring out the low and main jet sizes on this carb. currently it has a 40 low side and 46 main. I’m thinking this way to big.
wont idle and falls on its face when given more than 1/4 throttle.
recommended jet sizes Or suggestions?
thanks in advance
