a new to me 421

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.

HA I have the exact same machine sitting here, Does it have a wire with a loop to pull for the choke like mine, Also the oil level is checked by filling it to the top of the hole instead of having the dip stick, One I have is actually in real good shape and was given to me by a family member to get running and sell because they no longer wanted it and now pay neighbors to clear their drive. One main difference is mine does not have the large augers, Not sure if they were replaced but it has standard augers on this one which I found odd.

Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.

Dauntae: the choke lever is original on mine, and yes, the oil fill is old school, fill till it pours out.

Yeah, I'll replace the disc. Sometimes I get too cheap. I assume is just that larger nut to the left of the disc (when that machine is up) that holds the disc assembly on.

OH mine is original but may be a bit older, Not sure the year but here is the new carb with the carb box off, Wire was to turn choke on and off.

that looks like a 1979 version, one year older than mine. I have seen that type of choke lever.

Have you found the owner's manual for yours yet, Toro site has it for download, I am still wondering if the Augers on mine are the original or were they replaced. Have the sheer pins out to grease the fittings and all seems as it should so I wonder if this was around when they were starting the big drum augers.

looking here, it appears that the 1979 has the smaller drum for the auger than the 1980

vs

and the French version (but not English) of the 1979 user manual is available here: https://www.toro.com/en/parts/partdetails/?id=2770


for reference:

I get manuals here: https://www.toro.com/en/parts
I get year of mfr here: https://lookup3.toro.com/partdex/ind...oro&lang=us_en

You went even deeper than I did on the manuals, Mine is in really good shape but still plan to go through it like you to make sure all is well with it, Still have not tried to run it but was told by the family member who gave it to me it did run well before it sat a few yrs. Not sure what I will do with it, May keep it for my backup or for my girls son to use to learn to make a little of his own money (13 yr old LOL) But I def do like this old machine. Not sure I want to sell it as it's solid but not a big seller price wise but I def like it.
