Why is my Cub Cadet 500 Snow Blower engine running erratically?
- Rryan50Sep 10, 2025
To resolve inconsistent RPMs (hunting or surging) in your Cub Cadet Snow Blower engine, first ensure the choke lever is in the RUN position and that you're using clean, fresh gasoline. Also, drain the fuel tank and refill it with fresh fuel to eliminate any water or dirt in the fuel system. If these steps don't work, the carburetor may be out of adjustment or the engine may be over-governed.
