That is a Tecumseh two stroke engine, after the power products acquisition. It was likely built in the 1980s or 90s. Engines that look identical to that were popular on cheap two stroke snow throwers up until the early 2000s

Looks to be a West Bend Power Bee engine. Was a popular go cart engine of the 50's and 60's. Was also owned by Chrysler at one time. Search on YouTube and show engines on there compare.

I don't think so Chris. That Walbro carb with the cast bowl puts it about 1950-1960s ????? In the 1980s, Tecumseh used their own carb. Tecumseh was mixed up with a foreign company, might have something to do with it.

It's a Jacobsen. Have a few of them.

Dave G is correct, it is indeed a Jacobsen. I just looked through some pictures on my computer, your engine may have been used on a Jacobsen edge-n-trim or small reel mower. It might be a model 501, but I am not a Jacobsen expert by any means. The resemblance that this engine has to the later Tecumseh two strokes is uncanny.

Wow, thanks all, that's fantastic!! I'll start researching in that direstion. If this is an old Jacobsen I think these were pretty eliable little motors in their day. We had a reel mower that ran forever. I didn't realize they made them in white, I had only seen orange before. I think they were around 2.5HP? Was going to try it on a minibike

Is there a way to tell the difference between the 321 and 501? Can I use a "regular" muffler with it? Original is long gone. And, do I use regular non-detergent engine oil mixed in the gas 16:1, not 2-cycle oil? Thanks

I would use a regular 2-cycle oil ( not outboard motor oil ) mixed at the recommended ratio, probably 16 : 1. A quart of 2-cycle oil is made to be mixed and doesn't separate out.
