Hi, New member here. Not a kart racer but thought with all the experience on this board I might get a solution to my problem. I purchased a HF 459cc engine and installed in a UTV. Everything worked out well except the Carb. Couldn't get the needle valve to hold pressure. Tried fuel pump, graviity fed w/no luck. Kinda hit and miss. Never knew when the cylinder was full of fuel when you got ready to crank it. HF sent me two carbs, both of which were wrong. While still under warranty I got them to replace engine. Second one has same problem.
Any thoughts on a solution to my dilemna? Does anyone know if a different carb would work on this engine? Thanks for any responses!
