That's good thought on something to check. My little engine had a manual choke lever. But the Tecumseh here probably would have the choke tied in with the throttle linkage somehow.

Thanked 5 Times in 5 Posts's been a couple of years since I posted in this thread, but I wanted to follow up with how I finally fixed the problem.

I ended up purchasing an aftermarket carburetor. It is an exact replica of the original carb, and bolted on with no issues.

I've mowed the lawn twice now since I did the replacement, and have not run into the issue yet... I will follow up if it rears its ugly head again.

In the hope that this will help anyone else with a similar problem, I ordered this carb, also pictured below.
