Hey everyone, I have a quick question. I have a 1983 110 ATC and the engine needs quite a bit of work. I recently just looked at a 1981 (110) full engine that turns over nice and for a good price. My question is, Will the 81 work with my 83? Thanks.

 

Take a look at the parts books on line and compare the parts. A quick look shows the same crankcases but a different alternator, does it matter, who knows?
