Good To Know

Q: How do worn reed petals affect engine performance? A: Worn or chipped petals cause hard starting, erratic idling, and a noticeable loss of low-end power due to blowback into the carburetor.

Q: Are modifications to carburetor settings required after installing this valve system? A: While this unit is a direct fit, adjusting carburetor jetting can help fully optimize the improved airflow characteristics.
