Frequently Asked Questions
Q: Will this fit my Craftsman LT2000 with a 17.5 HP Briggs engine?
A: Most likely yes. The Craftsman LT2000 series commonly uses the B&S Intek 17.5 HP (model 31C707 or similar) with the Nikki carburetor this kit is designed for.
Q: My engine surges at full throttle — is this the carb or the governor?
A: Surging is typically a carburetor issue (lean condition from clogged passages) rather than the governor. Rebuild the carb first. If surging persists, check the governor spring and linkage.
Q: Does this kit work with E10/E15 ethanol fuel?
A: Yes. All components (O-rings, gaskets, diaphragms, Viton needle tip) are manufactured from modern ethanol-resistant materials.
Q: How do I know if my carb is Nikki or Walbro?
A: The manufacturer name is cast into the carb body. Nikki carbs typically have a removable float bowl with a center bolt. This kit is designed for Nikki carbs used on most B&S Intek singles.
