I tried to do a quick search and did not see anything I had not already found....just in case some one has some new wisdom to share...

 

Motor is in a late 60's early 70's garden tractor

 

Tecumseh HH80 110089C   8312  

 

From what I am reading,  am guessing 68  and 312 days into the year???

They changed how they did their serial numbers in/about 1970-71  (I know it was "by" 1971)  that is a later serial number  you got part of it right; 312th day of a year that ends in 8,  but unless there are about another 6 digits after a space   past that 8312,

 

it is definitely newer than 1968  its either 1978 or 88...  was there a letter after the 8312?

On my 1966 HH100 the number is 6060, which would make it March 1 1966.

How long did they use the "solid state ignitions" in them?? I was hoping this was an original motor......bush hog is probably a 69-71 from what I can gather.....well maybe the 8 is actually a 6 on it?......one can only hope!

First digit is year, next 3 is day of year - from the 4 digit serial number.  So it was built the 312th day of 1968.  Likely the tractor would be a 1969 model.  This way of dating only works if you know the decade they were built in, as the cycle begins every decade on the year digit.

 This also fits with the years you have found on build dates for the V4-8.....first year of production in 1969.

They switched from points to solid state in late 1967 engines.
