Improve Engine Efficiency and Throttle Response

Upgrading or replacing worn jets is one of the most effective ways to restore engine performance. A properly sized carburetor main jet ensures the correct fuel flow at high speeds, while pilot jets control fuel delivery during idle and low-speed operation.

Using the right main jet carburetor combination helps:

• Improve throttle response
• Enhance acceleration
