Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
- Kohler CH730 engines using 24 853 91-S
- Kohler CH740 25HP engines using the matching carburetor
- John Deere and other commercial equipment only when engine spec and original number cross-reference
Product Overview
A commercial mower that surges, floods, loses power under deck load, or sat through a season with old gas may need more than a bowl cleaning. This replacement is for CH730 / CH740 specification codes that use the matching linkage, intake, and fuel-solenoid arrangement.
Read the engine model and specification tag before ordering. Kohler used several carburetors across the Command family, and the mower brand alone is not a reliable fitment check.
This is an aftermarket replacement part and is not manufactured or supplied by the original equipment brand.

Compatibility Notice

Compare the original component, reference number, connector or mounting design, dimensions, and any serial-number or production-date break before purchase.
Frequently Asked Questions
Q: Will it fit every Kohler 25HP engine? A: No. Horsepower is not enough; the CH model, specification code, and original carburetor must match.
Q: Can a bad fuel pump cause the same loss of power? A: Yes. Check fuel flow, tank vent, filter, and pump before condemning the carburetor.
Q: Why does it surge at no load? A: A lean pilot circuit or intake leak is common, but governor and ignition faults are also possible.
