I ran across this question in the close queue which had these comments
I'm voting to close this question as off-topic because Small Engine repair is not in the site scope.
Although we do answer these questions quite often.
We've got, for instance, lawn-mower (70 questions at present), which is mostly about small engines and I've never seen anyone suggest the tag, let alone the topic, was outside the site scope. It seems very DIY, as long as you're repairing a small motor (and not a vehicle, i.e. Mechanics.SE). Community feedback would be helpful.
