Any suggestions?
Answers: Since it sat for so long, i would whip the time and go through the trouble to cart it apart and re-build it. You said it sit for three years, that is slightly a long time for deposits from the gas to make homes within all the small ports and feed on a carb of that nature. And, contrary to popular belief, aerosol brake/carburetor cleaner WILL hurt rubber seal. It CAN and WILL harden them. IF you want to do this yourself, catch a manual, filch good log, buy the best parts, and when it comes time to actually verbs the body and all the small METAL parts, use mineral spirits or Naptha and a nouns blower in conjunction next to a air compressor. Good luck
only just get some carb cleaner contained by a can from your local auto parts store, use it and a soft brush, it takes some time but it's worth it surrounded by the end.
