HS50 question

[Bored2048]

Since its late and I cant take any good pictures....i found the egine numbers on my minibike and maybe it will narrow down my search on what kind of bike it is, but also where I can find parts and maybe interchange parts....here is what is stamped on the engine, maybe some can tell me when it was made?
HS50-67124E SER 7079B.... again any information would be helpful thank you.

Its a small block 5 hp tecumseh motor - you probably already knew that. Age ? Not sure, but I would guess the numbers you have could tell you if you can find someone that knows how to decifer them. Interchange of parts ? I dont think tecumseh changed much at all on this series of engines, so interchange among any other HS 50 and I think external parts of HS 40 engines should be pretty good. Hope this helps.
