Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Briggs & Stratton 21B000-series vertical-shaft OHV engines using the matching Nikki carburetor
Product Overview
Surging, hard starts, flooding, or an engine that dies when the choke opens can come from varnish, a worn inlet seat, or blocked passages inside the carburetor. This complete assembly is the next step when fuel delivery, ignition, compression, and intake leaks have been checked.
21B000 identifies an engine family, not a carburetor part number. Match the full model/type/code, Nikki body, solenoid, choke, and linkage.
