Product Overview
A mower, tiller, pressure washer, or utility engine that starts on primer fuel but will not keep running often has a fuel-delivery problem. If fresh fuel reaches the carburetor and spark, compression, air leaks, and governor linkage are good, the original carb may be varnished, warped, or worn beyond a simple cleaning.
This replacement is used on select Briggs flathead and utility engines in the 4-7HP range. Horsepower alone does not confirm fitment. Use the engine model, type, and code stamped into the shroud and match the tank interface, primer, linkage, mounting holes, and reference numbers.

Frequently Asked Questions
Q: Is 520-964 a Briggs & Stratton number? A: It is a Stens cross-reference; the Briggs numbers are listed separately.
Q: Will horsepower alone tell me if it fits? A: No. Match the stamped engine model, type, code, and carburetor layout.
Q: Why does the engine start with primer but die? A: Fuel may not be reaching the main circuit, but tank venting, air leaks, and governor problems can also contribute.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
