Hey so just purchased this kart for my kids and everything seemed good had to use starter fluid to get it started now it starts every time as long as I have the choke on. So problem I am having is my son is 4 and never had a kart to I wanted to adjust the governor so that even if he pressed the gas fully he wouldn’t go very fast till he learns to control it. Well no matter what I adjust, tighten or loosen when the gas is pressed the kart eventually gets full or near full speed. I have tight the screw circled al the way and the kart won’t move but as soon as I loosen it enough the kart just accelerates slower but top end is the same. So what am I missing? Not adjusting? Thanks in advance!
