Your cart is empty.Jet kit for Fits Honda , clone, GX340, GX390, and Predator 420cc engines. Includes two jets: .041" (#104) and .042" (#107). These jets are larger than stock and give a good baseline when you have added a header and air filter kit.

comes with numbered jets 41 & 42. I used the 41 jet and engine runs fine with original air cleaner. Back story- I had over enlarged my original jet to 1/16 inch (my smallest drill bit size) which made the engine run rough at any speed over idle.

Try to use these for my Predator 420 with a header and intake now the motor will not run unless the choke is half on this means the motor is starving for fuel these will not provide a good Baseline for a predator 420 he will really need to start with at least a 44 45 or 46 to have a smoother running engine after a header and intake is installed on your Predator 420
