Carb Parts FAQ
What parts usually fix a hanging idle or inconsistent idle?
Most commonly: worn o-rings/seals, a leaking fuel screw o-ring, or general wear that needs a refresh.
Start with rebuild items and verify jetting is correct for your setup.
What parts usually fix an off-idle bog / hesitation?
Off-idle issues are often tied to pilot circuit and accelerator pump setup.
Pilot and leak jet selection—and pump wear parts—are a common solution path.
Do I need a full carb rebuild or just a few parts?
If the carb is leaking, has unknown hours, or is inconsistent through temperature/altitude changes,
a refresh kit + correct jetting is usually the quickest, most reliable fix.
Can Tokyomods rebuild and modify my carb if I don’t want to DIY?
Yes—if you want a turnkey solution, use our carburetor modification service.
