Motor slide -
In the winter, I start the lawn mower every two weeks and let it run for a minute. When it’s not winter, I do the same with the snow blower, and I run the portable generator for a minute every two weeks regardless of the season. I set an auto-reminder in my phone so I don’t forget, I do all three at the same time, and I’m disciplined about not pushing off the chore. They all start like new every time so far, so am I still likely to get gummed-up motors?
You’re doing the right thing. Running the motors for a few minutes helps keep the fuel line a d carb clean.
Most of us don’t do that - thus, using up all the old fuel before storing the machine.
