Product Overview
If the mower starts on spray but will not continue on its own fuel, hunts while mowing, or floods after sitting, the carburetor becomes a likely repair after fuel flow, spark, compression, and the shutoff solenoid are tested. This assembly is intended for the matching 18.5 HP engine configuration.
Machine names alone do not guarantee fit. These mowers were built with different engines, so match the full Briggs model/type/code, carburetor shape, solenoid, choke, and linkage.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Frequently Asked Questions
Q: Is the mower model enough to order this carburetor? A: No. Verify the Briggs engine identification and original carburetor.
Q: Why does the mower start with spray and die? A: Poor fuel delivery is likely, but the filter, pump, tank vent, solenoid, and carburetor all need checking.
Q: Will it fit a Craftsman LT1000? A: Only if its engine and carburetor match; LT1000 is not automatically interchangeable with the listed applications.
Q: Can fuel in the oil come from the carburetor? A: Yes. A leaking inlet needle can fill the crankcase; change contaminated oil before running.
