When I bought my used Ariens from the local dealer soon after the blizzard of '93 he told me that the po had repowered the machine and then traded it in on a new one.
I searched all over the net and can find any way to tell when this engine was made.

Thanks!

The engine serial number, 2175D, says the engine was assembled at Tecumseh
on "the 175th day of a year ending in 2"
Which could be 1962, 1972, 1982, 1992, or 2002.

Tecumseh could have helped us all out SO much just by using a 2-digit date code!

We can rule out 2002 because of "soon after the blizzard of '93"
and its not a 1962, because Tecumseh wasnt making any 8hp engines then,
so we are down to '72, '82 or '92.
Should be able to whittle it down further with features on the engine..
and maybe we can figure out what years the model HMSK 80 was produced.

Can you post a photo of the whole engine?

I bet it's a '92 then...my '89 8Hp is an HM80.

The recoil starter and gas tank are consistent with late 80s to early 90s Tecumseh. I will never understand why Tecumseh used a one digit date code, You can tell when a Briggs & Stratton was built right down to the day.

T I will never understand why Tecumseh used a one digit date code,
I think it's because people just dont think long-term..
In 1962, using a "2" for 1962 and a "3" for 1963, etc, would get them through a decade just fine! ;) In 1970, seeing a "3" on a tecumseh date code wasn't a probem..
of course it means 1963..it cant mean anything else! its only now, 40 to 50 years later, that we are starting to have a problem..

I have started to run into this issue with genealogy..
All of our lives we have written the year as 2-digits..we might write on the back of a photo "Aunt Janet, 6/21/87".

In our lifetime, we will absolutely understand that has to mean 1987.
it cant mean anything else! no problem..for us! ;)

But in another 300 years, people will wonder if that photo was taken in 1987? 2087? maybe 2187? we arent sure..
If only people hundreds of years ago had used the full 4-digits, we wouldn't have this problem! ;)

This has already happened!!
Someone on a train forum thought a B&W train photo marked with the year '60 was taken in 1960..nope, it was actually 1860.

I have begun writing the dates on the back of all my family photos, for my genealogy research..
I have family photos from the 1890's through the 1970's..I write the FULL 4-digit year on them!
even though its totally obvious to me that photo of my sister was taken in 1976, not 1876 or 2076..
and I could write '76 on it and no one would be confused...
its entirely possibly that my sisters descendants 300 years from now might not understand which century that '76 was in..
