Soaking Onan Carb in Acetone?
Assuming I do a tear down and remove the seals/plastics, has anyone had good or bad experiences with small engine carbs and acetone? I've got what I suspect is a gummed carb on my Onan 4K, after it...

Kit, from what I've read over the course of years the 4KY carb is tricky to clean. We had a certified ONAN tech here who said some of the passages have right angle turns in them and difficult to impossible to clear out. Kinda like the first time I worked on a Toyota carburetor. Could barely get the wire from a twist tie in some passages. I think I plucked a piece out of a wire brush. The Pontiac we had, I think I could about use coat hanger!
Carb replacement makes sense too, if you could get parts but had to pay shop labor for the tinkering. With new, there's a far better chance the thing'll run right. We pay, but get happier the better and longer it runs.
Consider doing what some of us do - fuel stabilizer treatment every tank. I know that on ours, it was a matter of weeks (OK maybe 8 or so) after a new carb that the genny wouldn't start again. I fought it on and off a couple years before replacing the carb.
For anybody interested, changing carb on 4KY is pretty easy with a couple odd tools, a couple tricks, and a good picture of how the linkage goes.
