Description

168F-47 Lowside/Epa Jet for Ruixing Carburetors (Choose Size)

This jet is for the Ruixing clone carburetors. Not guaranteed to fit other clone carburetors. Using the Tillotson PK-1 clone carburetors, they will use a different Lowside/EPA jet.


Low Side Tuning is a little more difficult than the main jet. The Low Side is going to affect the idle and low-speed acceleration. So we have two recommendations for tuning the low side jet.


For better acceleration, use .028-.034; this is almost exclusively for racing applications. 

The idle will be rough, and, if left to idle, can foul plug fairly easily. As long as the engine is accelerating when going to wide-open throttle,e you can keep adding low side jet. If it bogs then accelerates hard, then you could be rich go down a jet. If it's flat and slow to accelerate, then it could be lean, go up a jet. 


For better idle quality while still picking up some power, use .019-.022. We usually recommend those running mini bikes or recreational karts that need them to idle.
