Carbhub 591925 is a complete aftermarket carburetor replacement kit designed to restore fuel delivery for small engine models that list part numbers 698479, 693518, 698475, and 591925.

If your Craftsman tiller, chipper, or similar engine is running rough, flooding, or failing to start, a worn or clogged carburetor is often the cause. This Carbhub assembly ships with the carburetor plus the key consumables—air filter, fuel hose, fuel filter, shut-off valve, gasket, and clamps—so you can replace the unit and associated parts in one repair session. It is an aftermarket (non-OEM) part, so confirm model compatibility before ordering.

How will this carburetor improve engine starting and idle?

Replacing a faulty carburetor can stabilize the air-fuel mixture, making cold starts easier and reducing stalls at idle. The included gasket and clamps ensure tight seals to prevent vacuum leaks that often cause erratic idling.

• New carburetor body tuned for original specs
• Fresh gasket to eliminate air leaks
• Clamps and fuel hose to restore secure fuel flow
• Fuel shut-off valve to stop leaks during storage
