Several months after a local repair shop worked on my snowblower two winters ago it started having a problem where the choke will slide out when it is running and flood the engine. We quickly push the choke back in to keep it running. Now it happens constantly. I've disassembled the choke handle assembly and found several small strips of electrical tape on the choke handle where it slides out. This didn't look like it was from the factory and there is no return spring to keep the choke disengaged. Should there be one?

Also, is there a picture posted showing the carb and what to clean for this model?

 

Electrical tape is NOT factory. Sounds like who ever fixed it had the same problem and did a quick temporary fix. There should be a spring wrapped around the choke shaft. Here is the parts break down for you snowblower.

Thanks for the links and additional information. I've got the carb jets soaking in cleaner and I'm off to find new fuel hoses, filter, and choke spring.
