The first digit of the D.O.M. Is last number of the year/decade it was made. the next three numbers equate to the numeric day of the year, like a Julian calendar. I would have to say your engine was made on the 114th day of 1991 or 2001, Tecumseh changed over to 5 digit codes in 2004 and I'm pretty sure this style wasn't around in 1981.

2001 would be my guess. the literature that belongs to the snowblower is dated 5/2001. how do we account for the engine meeting 2006 emissions?

I just noticed that and was going to say something about it.

For what it's worth, this is the style labels on engines after 2004. I'm guessing the pre-2004 D.O.M. is the same minus the assembly line/shift code and individual unit#.
