Specs At A Glance

Good To Know

Q: Why should I replace rather than rebuild my old carburetor? A: Over decades of use, internal channels can become permanently blocked with varnish, and the metal throttle shafts can wear out, causing vacuum leaks that a simple rebuild kit cannot resolve.

Q: Do I need to adjust this carburetor out of the box? A: While the carburetor comes with pre-set factory settings, minor adjustments to the idle speed and air-fuel mixture screws are typically required to match your specific engine and altitude.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
