Thanks Putts I wish I would have read your #3 before ordering a new thermo choke with the premium rebuild kit from Mike's. But I will order one within the week. So I soaked the carb in penetrating oil for two days scrubbed what gunk I could get off with a toothbrush and disassembled it. So about the cleaning process I work in a machine shop, and we have ultra sonic tanks with 160° lenium (which is safe for aluminum) I wonder if that would work for getting the hard to reach spots. Also while I had the carb at work, would there be any benefit to resurfacing the gasket surfaces to true them up a bit? And extech my shop manual just came in(wow tons of info). You had mentioned earlier about a nylon pin. I am looking at everything in front of me that came out of the carb and there are no nylon pins. Could that not being in the carb have something to do with the secondaries virtually being rusted shut? Thank in advance all.
