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...

You do not have to pull an Onan Carb to fix clogged orifice jets. YES, orifice jet holes are clogged. Your symptoms are exactly what is caused by a gummed up carb. The reason Onan does not sell rebuild kits is because of our favorite state--California. 25 years ago California, had the most restrictive Emission laws, and Onan did and could not build Carbs that would meet California and the rest of the USA. So, Onan adopted the California standard which mandated sealed carbs. If you are careful you can remove the Carb Bowl, and then unscrew the Main jet. then soak in carb cleaner and blow it out. You can hold it up to the light and see if all 16 holes are open and clear. You then reinstall and you are good to go after making minor adjustments on the mixture main screw. SEA Foam does not always get all 16 open and clear. Doug
