FAQ

What engines does this PZ22 carburetor kit fit?

This kit is designed for Briggs & Stratton 5HP Flathead engines (Model 13) with the wide bolt pattern intake flange, commonly found on late-model Raptor blocks. It will not directly fit early narrow-bolt engines without modification.


What are the benefits of using a PZ22 slide carb over a stock carb?

Yes! Each PZ22 in this kit is pre-tuned for use on stock to mildly built flathead engines running on gasoline, giving you a plug-and-play upgrade out of the box.


What type of air filter does this carburetor require?

This carburetor requires a 32mm inside diameter air filter. The filter is not included but can be purchased separately.
