Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I saw a posting about a week ago on Craiglist, someone was clearing out their shed, and was offering an Ariens single stage snow thrower for free. I was fortunate enough to be the first one to call. By the time I got over there, he said he'd gotten about 15 calls about it, and he got 2 more while I was getting it in the car. He said it ran when they put it away 2 years ago, but wouldn't start. It turned out to be an SS322. Has a Tecumseh HSK600 engine, 98 cc, 2-stroke, 3 hp.

Got it home and tried the obvious/easy stuff. Drained out the gas, which looked disconcerting (had some dark stuff that stayed as a liquid layer at the bottom of the tank and would not mix in with the rest of the gas). That didn't help. It would start using starting fluid or carb cleaner, and run for a few seconds, but that was it. I measured about 90 psi compression. The cylinder & piston looked good to me, looking in through the exhaust port.

Long story short, I got a rebuild kit, and did my first carb rebuild yesterday. Opened it up and was horrified to find a bunch of green stringy goop on the float and bowl, and a whole lot of nasty brown globs at the bottom of the bowl. It looks like someone took the bowl off previously, and sealed around the o-ring (which was still installed) with something, maybe silicone? The o-ring was covered in this stuff, and it was visible on the outside of the o-ring, before removing the bowl. The gas seemed to have eaten that, and the carb was just a real mess (everything was plugged, etc). Took a whole lot of carb cleaner, and soaking the carb in Berryman B-12 after removing the plastic/rubber stuff, plus scraping stuff off of it, etc. But finally got the insides cleaned up. The only question was about reinstalling the plastic (emulsifier?) tube that goes up from the main jet. I had 2 new o-rings in my kit, one seemed a bit bigger than the other. I put the bigger one at the "back", down by the jet. Put some oil on them, and pushed the tube into the carb by pushing it with a punch to try and support the rear o-ring. It kind of slipped off the back of the tube (did not stay in its groove), and ended up between the tube and the main jet. I hope that's OK. I didn't want to risk damaging the o-rings by driving it back out and trying again.

Once I was ready to reassemble it, I discovered a hole in the freshly-cleaned carb bowl, which had some serious corrosion on the inside. Picked up a new bowl today.

Reassembled it tonight, took it outside, and it fired up on the second pull! I was thrilled. Wasn't sure if my first carb rebuild attempt was actually going to work. It's not running perfectly smoothly, it seems to be 4-stroking a bit. The carb is not adjustable. I'm hoping it will smooth out when I put a load on it. It was about 60F out. I may put some Seafoam in the gas, to see if I can finish removing anything that might be left in the carb. I need to replace the auger belt, and check over the rest of the machine. But I'm happy, maybe I'll get to try a little 2-stroke single stage machine this winter. It would be cool if this was the 5hp version, but I certainly can't complain, for the price :) I have an electric Toro Powercurve 1800 for clearing the deck. Perhaps this could replace the Toro.

Anyways, I was just happy about it finally starting up, and wanted to share.

Just wanted to post an update. I changed the gas to my existing 45:1 mix (gas cap says to use 50:1), and gave it a new spark plug. Checked the compression again, it was about 88 psi. Squirted in some 3-in-1 oil, and it went up to maybe 93 psi. I'm happy with those, I guess. The machine is from '97 or '99, I have no reason to think it has lots of hours on it. I don't know how to tell when the paddles are worn out, unfortunately. Is there something you can measure? If I raise the handle, the paddles hit the ground and it pulls itself forward, as they should. This is my first gas SS.

Put on a new belt, got that all adjusted. I tweaked the governor a bit, from 4000, where it had been, up to what is apparently 4600. The spec is 4300. I was just trying to get a bit more speed on the paddles, but I can drop the governor back down if the extra speed will cause a problem. I thought about adding a string to let me manually open the throttle for better flinging, but I will leave it as-is for now. I did try manually closing the throttle, and it idled down smoothly, to about 2800 RPM. So I assume the idle jet/passage is working properly. I am hoping the surging will go away once it has a load on it.

grump, thank you for the info on the recall. I talked to Ariens, gave them the model and serial, they said mine was not part of the recall, so that's good.

I think it's ready for winter. I am going to give my electric Toro SS to my parents, so this will take over deck-clearing duty. I will also try it on the driveway, maybe it will get used instead of my two-stage for light snows.

Yo Red:

That machine should be great for a deck.  I'm using the  MTD single stage machine on my deck if the snow accumulation is sufficient enough to cause me to fire it up.   The nice thing with a blower on the deck is that you can fire the snow over the balusters and railing rather than shoveling through.  I built my deck with snow in mind so I left a 4" space between the deck surface and the cross member used to attach the bottom of balusters.  I can shovel most snow under it.   However, when we get a big dump, that's not a happening thing so the SS machine with the "speed string" takes care of that.  Another bonus is that the snow is thrown a fair distance from the deck.  My deck is a good five feet off the ground but by mid winter, the snow banks are usually right up to the surface and snow isn't as easily shoveled off. 

Yeah, you're going to appreciate having a light SS machine for deck duty.  Put a string on the governor if it doesn't fire the snow fast or far enough for you.  You'll be all smiles when you crank it up!

My only concern about the machine is having to carry it up the ~10 feet of stairs to my deck (which is, not surprisingly, ~10 feet off the ground), including the turn in the stairs. I have a feeling that will be awkward at best, in the dry weather. Add some snow/ice to the stairs, and it could get iffy. I don't really like the idea, but I could store it up on the deck, under a tarp, to avoid carrying it up & down each time. My electric weighed about 25 pounds, which was easy to move around. This is much bulkier (so it's awkward to pick up), and weighs 60 lbs.  We will see how it works out.

I park mine on the deck all winter under the eave of the house.  Don't even cover it. 

You'd be better off just leaving it there for the duration.  Just buy one of those big inexpensive plastic tote boxes and throw that over it or modify it to use as a cover.  That will keep it out of the elements.
