Each decade that passes, fewer people report knowing how to drive manual carburetor chokes.
Everybody who has a piece of small power equipment with a manual choke knows how to operate any other thing with a manual choke. I suspect that the number probably peaked in the last 20yr.
It was a cold morning, and wouldn't start.
The issue wasn't not knowing how to use a choke, but not knowing that it had a manual choke.
