I us to put a 1/16 drill bit in the air hole and let the choke plunger down till it just touch the drill and then locked the cable. This left about 1/16 " free play in the cable & stopped any chance of chocking the engine when hot. works real well on most sleds. Good luck!! be sure you have free play in the cable & choke plunger does not touch the bit this gives you max choke as long as the hole is wide open. be sure to have choke on when doing you settings.
