Application:

The pilot jet plays a critical role in carburetor performance, metering fuel for engine starting, idling, and low-speed operation. Proper pilot jet sizing is essential for crisp throttle response, smooth idle, and eliminating common issues like surging at low RPM, bogging during throttle opening, or difficult starting. This #52 size jet allows you to fine-tune your carburetor to compensate for modifications such as aftermarket exhaust systems, high-flow air filters, or changes in altitude and atmospheric conditions.
