So I have a go-kart with the predator 6.5 Hemi and it runs like crap. It has a air filter kit and exhaust kit. I’ve purchased your .036 & .037 with E-Tube kit. I tried both of them and still runs like crap. I tried every combination with the jets and E-Tube that I purchased. It start up fine and...
