Frequently Asked Questions
The bleed pilot jet controls the amount of air that bleeds into the pilot circuit, affecting idle quality and low-speed throttle response. It works in conjunction with the pilot jet to fine-tune the fuel-air mixture at idle and low RPM.
Signs include rough idle, difficulty starting, poor low-speed throttle response, or if the jet is visibly clogged or damaged. Cleaning may resolve issues before replacement is necessary.
Yes. The 62.5 designation is specific to this jet size. Using an incorrect size will affect carburetor tuning. Verify your carburetor model and original jet size before ordering.
Often yes. Soak in carburetor cleaner and use compressed air to clear passages. However, if damaged or heavily corroded, replacement is recommended. These jets are inexpensive.
Not necessarily. If only replacing a worn or damaged bleed pilot jet with the same size, no other adjustments are typically needed. However, if tuning your carburetor, you may want to evaluate all jets together.
