Today I was cleaning up from the latest storm and noticed it sputtering, like a faint backfire, and suddenly it just stalled. I tried starting it but it wouldn't start. I pulled the plug and checked for a spark but I didn't see one. That could be due to the bright sunlight and snow glare. I let it sit for about 30 minutes while I, yes it's true, I used a shovel to move the snow. After my workout, I was able to start it but I had to fool with the choke to keep it running. After a few minutes it suddenly stalled again.

I'd appreciate it if anyone could provide some clues as to what's causing this machine to stall because shoveling snow is over rated.

Thank you

Thank you for taking the time to read and respond to my message.

It was fresh gas when I brought it to the shop and it was stored in a clean container. Do you have a suggestion of how I can clean out the fuel tank? I suspect the repair shop had to drain the tank to replace the fuel line and shut-off valve.

I'll try loosening the fuel cap and see how the machine runs. It always stalled when there was a load on the machine. I don't recall seeing a vent hole in the cap however, there is a silver colored concave disk on the underside of the cap. Is that there to prevent the fuel from leaking out of the vent hole that I haven't seem yet?

I read somewhere that the gasket between the carb and engine could be damaged or the carb has loosened up.

It's just odd that it stalls suddenly...no sputtering, struggles to stay running or warning, it's immediate.

I just hope that it's not July by the time I figure this out.

Thanks again

Not sure this is your issue since you recently had it services but I figured I'd post anyway for those who may experience this.
