Frequently Asked Questions

How many carburetor throttle-shaft felt seals are included?

6 felt shaft seals are included. Count the matching seal positions on the exact carburetor assembly before ordering additional sets.

What problem can worn carburetor shaft felt seals cause?

Hardened, missing or damaged shaft felts can allow unmetered air or dirt around the shaft, contributing to an unstable idle or difficult synchronization. Confirm shaft and bore wear as well as seal condition.

Is this a complete carburetor rebuild kit?

No. This set contains only the 6 throttle-shaft felt seals; jets, float valves, bowl gaskets, passage O-rings and other carburetor service parts are not included.
