I picked up a 421 for $25 that leaked gas. 1980 model. Seems to have good compression. I don't need another blower, but, well, you guys know that doesn't really matter. The PO had installed that front steel bar, not really sure why. The skids and scraper will make it through this winter. Belts seem ok, I'll see if I have spares. It also had some spot painting done, I will probably disassemble and repaint the auger and housing in the spring. I drained the gas and oil. I took off the carb, ultrasonic'd it in soapy water, then blew it dry. Will fully disassemble, clean with carb cleaner, and rebuild with kit. Got new fuel lines run. Will replace carb and muffler gaskets. I took a look underneath, looked pretty good, except for the friction disc is a bit worn, and has a small crack/chip. Do you guys think it will survive till next year? Also, this model calls for 3 oz of 90W in the auger gearbox, I let it drip out for 30 minutes, and seems like only 1 or 2 oz came out. I will measure later on just to see. Glad I drained it, will refill properly.
