Tecumseh Engine ID

We have an older 70s to 80s Ariens with a Techumseh.
It seems the previous owner(s) when someone, at some point, decided to repaint the machine and removed all ID decals or plates. if it wasn't removed it was painted over and no way I could retrieve any numbers
There are no model or serial numbers on this machine NOT EVEN stamped in numbers on the air shroud or recoil.

I swear this engine is a transplant from a rototiller or something.

IMO all Ariens are Orange with white engines and trim. Correct????
THIS Ariens engine had an original orange paint and repainted black at some point. Fortunately, the points and carb kits are typical but we wanted (not needed) to replace the valve springs.

Once we get this back together, I'll post a picture. I want to put an engine model number on the engine with my Brother label maker for future service. The condition of this machine is the typical good ole strong machine Very few parts needed replacing, friction wheel and tune up stuff. Picture coming soon.

I forgot to mention. This is a 24"
The Ariens data sheet suggest about 1971 series make it a 2.7HP and a post 1992 series makes it either a 3.5 HP or a 4.0HP. I'm leaning towards a 3.5HP.
Opinions please..

I don't think ariens put engines under 5hp on 24'' blowers. Can you post pic of your blower and engine?

Ok, I got into the actual Ariens website that denotes the models and series numbers per year and other info. Like I said any numbers we had were either sanded off years ago or just destroyed.

Now, the previous machine we just refurbished/restored was a newer model of a 24" and we believe that it's a 5.0HP. This engine "appears" to be smaller. I suppose the real reveal would be to remove both heads and check each bore to see how different they are or are not.

If, this Techumseh engine is off a rototiller could it be a 3.5HP?
I understand what you're saying but I really think this engine is a transplant from something else, other than a snowblower. That's if my suspicion of engine color means anything.

I can get the cylinder bore tomorrow.

Photos would be a big help!
we can probably pinpoint to within 5 years just from a photo alone..
yes, Ariens had engines smaller than 5hp on 24" models..
3.5 and 4HP were used at times.
Orange & White paint scheme was 1960 - 1979.
1980 and after is Orange & Black.

Here are a few pics of this engine including some of the Ariens machine. Needless to say it's not complete yet.

Remember this engine was originally either black or orange and repainted the other color. We stripped it down and now it's all white. Yes, I know the recoil is also upside down

Another quick question: I neglected to document a few things during tear down and the starter was one. Note to self for the future
Does the power cord, leave the starter at the top or the bottom of the starter before it heads over to the control panel? I may have to pull the starter and twist/rotate the back plate to correct things. Oops....

BTW the Cylinder bore is 2 1/2 inches

To me it looks like a newer 5hp. I could be wrong but i have never seen a snowblower with a starter under 5hp.

Ok, that makes sense. BTW we painted the starter orange ONLY as a personal decision to further make this machine 'pop' as far as color scheme.
Is that wire upside down?

Thanks so far...

Its a 1974 to 1978 22,000 series:

The Ariens 1960's and 1970's Sno-Thro info site - 22,000 series

That series ran 1969 to 1978, but the bucket pegs it as a '74, '75, '76, '77 or '78.

Engine looks original..probably a 4 or 5 HP.
are you sure its a 24" bucket? looks like it might be a 20"..

its very close to a model 922020 or 922022..(and it could actually be one of those)
all of the 22000 series are very similar, not much variation, these manuals (links below) cover all the later models in the series..so these are your actual manuals! even if you dont know the exact model:

http://apache.ariens.com/manuals/PRM%2022000.pdf

http://apache.ariens.com/manuals/022168B.pdf

One last place to try to search for a model number..
at the rear of the machine, where I have "tractor tag" marked in this photo:

http://scotlawrence.smugmug.com/phot...49_R8eeZ-O.jpg

Try looking very closely and see if you can find any numbers stamped right into the metal..thats the only place numbers were actually physically stamped, in addition to the tags..here is what the stamped numbers look like:

That's all great info to help us identify. All our original tags were eoither sanded off or painted over resulting in being useless

Thanks for your help
