Tyler, I'll have a look. Definitely an engine noise. Nothing too serious sounding, just not the typical noise, like it's worn somewhere from high hours.
I might mow my lawn with it if I can get the revs under control. The blades will still cut, they just won't send the clippings into the catcher well.
Throttle feels very stiff and creaky. Don't know whether it's the cable or the butterfly end . Probably both.
Another job for my 3 in 1 oil.
