Why This Kit is Different
Unlike other rebuild kits that only cover basic Performer 1400-series, this kit includes the bowl cover gasket specific to Thunder AVS and late-model Performer carbs. The AVS (Adjustable Vacuum Secondary) carbs have a removable secondary bowl cover requiring an additional gasket not found in standard rebuild kits.
Frequently Asked Questions
Q: What's the difference vs the 1400-1409 kit?
A: This kit adds the bowl cover gasket for Thunder AVS models (1801-1826) and includes both 30cc and 50cc accelerator pump options.
Q: Does this fit the Thunder AVS 1806?
A: Yes. The Thunder AVS series (1801-1806, 1825-1826) is fully covered, including the bowl cover gasket and correct accelerator pump configuration.
Q: Will this fit my 1477 off-road carburetor?
A: Yes. The 1477 500 CFM off-road Performer is covered. This carb has unique venting for steep-angle operation.
