Why It Matters
A 32/36 that bogs or hesitates the moment you open the throttle is usually short on its pump shot, not out of tune elsewhere. The pump jet size sets that shot: step up to cure a tip-in hesitation, step down to clear a rich bog.
Installation Notes
- Direct-fit brass jet for a clean swap in the carburetor's accelerator pump circuit.
- Match the squirter type: this is the double-squirter version. If you are unsure, contact us with your carb and engine before ordering.
