Mend Craftsman Eager1 Engine Stalls Air

Engine stalls when the air cleaner is installed!?

I just fired up my 18 year old Craftsman Eager1 lawn mower and it would run for a few moments then stall. I put in fresh gas, and a new plug but still no luck. It ran fine all last year. When I pulled off the air filter it started and ran fine. I bought a new filter and after I installed the fresh air filter it still stalls. I am thinking this might mean that an engine valve is leaking and the extra resistance with the air cleaner installed limits the air that can be pulled through the carb thus starving the engine for fuel. Is this possible or is there a more likely and cheaper resolution? Thanks!

Thanks Rick. I will attempt the operation this weekend!

Regards,

Sounds like the carb needs a good cleaning, or better yet overhauled. Kits are available from any small engine dealer.
You'll need your model number and type number. When small engines sit for extended periods of time the fuel in the carb evaporates leaving behind varnish that clogs the tiny passages inside the carb. Only way to fix it properly is to rip it apart and rebuild it.
