Frequently Asked Questions
The low speed (pilot) jet controls fuel flow during idle and low throttle conditions. It affects idle quality, throttle response, and low-speed running characteristics.
If your engine runs too rich (black smoke, fouled plugs) or too lean (hesitation, popping) at idle and low speeds, you may need to change jet sizes. Consult your carburetor tuning guide or service manual.
Higher numbers = larger orifice = more fuel flow. A 140 jet allows more fuel than a 130. Typical adjustments are in 5-10 size increments.
No. Verify your carburetor model accepts FN-series jets. Different Mikuni carburetors (VM, TM, TMX, etc.) use different jet styles and sizes.
Usually yes, though some applications allow access without full removal. Consult your specific vehicle's service manual.
