PSA: Air filters do not last forever
#1
The other week I selected a lawn mower from the shed, mowed about 1/2 hour then I stopped to do something else.

I come back to complete the mowing, its starts on the first pull and I'm mowing for 30 seconds before the engine stops. Won't start. Of course I had just refilled it with gas. And yes we only ever use enthanol-free here,

I pull off the air cleaner cover and 1/4 of the air filter is ... missing.

No evidence of mice (and they can't get into the air cleaner.)

***

I remove the carb and spray it down. Looks OK --- zero evident of paper --- reinstall, will not start. I pull the spark plug and it's dry. After all that pulling and pulling of the recoil and the spark plug is dry. Fuel made it into the fuel bowl, just not out. Float and needle valve seem fine.

Today disassemble the carb, take out jet and emulsion tube, and idle circuit plug and spray it all out. Upon reassembly and several pulls, it fires up.

I'm considering buying a motorcycle this summer that has a carburetor. I might need an intervention.
