Help Identify 2 stroke engine

I bought this thing a little while ago for $10. Anyone have a clue what brand? What did it power? And when I said its running to rich I meant lean

Vid is crap. Got good CLEAR pics?

 

[karl]

I will get some better pics soon

It's shaped kinda like a clinton..

X2 on getting in the way of the light. A trouble light held in your other hand beyond the camera's view would be an immense help.

Well lit pictures would be more beneficial than a vid..

I do not see Clinton related anything...

I gonna run out there now and snap a couple pics

 

[karl]

It was dark out and the barn was locked, and the motor is mounted to a frame so I blindly took the photos, there still crappy but better than the movie

[B man]

Good runner at 2.5 hp.

Put what together? engine or exhaust?

 

[karl]

The pull start, exaust, and gas tank

First Jacobsen I had came with a gear reduction on it and was unusable.
I was unbelievably fortunate in finding a short block on Ebay for about $19 (delivered).
One of the best 2 cycle power plants I've ever worked on.
Engine in pic has a recoil (and other mods) but is basically identical to your engine.

 

[karl]

So should I put it on a mini bike or should I keep it together?
And do you want another Jacobsen j-321 ? lol

Use it for a mini bike, gokart...or anything else.
They are tough little mothas' and can take a beating.
The original carbs were Tillotson bowls or Walbro's and were very restrictive. I use a Tecumseh diaphragm carb with a Craftsman mower air filter.
As much as I love my Clintons...the Jacobsen has them beat.

Ok thanks for all the help
