Gas engines and gas engine parts for construction equipment: complete Honda GX engines from the GX100 through the GX690 V-twin, Kohler CH440 replacements, and the recoil starters, starter assemblies, filters, and spark plugs that keep them running on the job.
This is the full gas section, engines and parts together. If you already know which side you need, go straight to complete gas engines or gas engine parts.
What's in this section
- Complete engines — Honda GX100, GX120, GX160, GX200, GX240, GX270, GX340, GX390, GX630, and GX690, plus the Kohler CH440 in 3103 and 3302 spec builds

Match parts to the engine, not the machine
Filters, recoils, and plugs follow the engine, not the mixer or saw it is bolted to. Start with the model stamped on the crankcase or the recoil-shroud decal — GX160, GX270, CH440 — then match the factory part number digit for digit against the one printed on your old part. When a listing carries a number like 28400-Z4M-306ZB, that number is the fitment. Running a Honda-heavy fleet? The Honda engine parts section carries the deeper GX coverage — carburetors, coils, gaskets, and valves by model.
