Photo Air-Cooled Wisconsin BKN Info Please

A tech ed teacher at the high school I work at stopped me after school Tuesday of last week. He told me that he has been cleaning up some of his old stuff and wondered if I could help him lift some junk into the dumpster. After putting in some wood and metal bits we came to an engine, he said, "either help me lift this into the back of your truck or in the dumpster - its your choice." Well I couldn't say no... so now I have this small engine and really don't know anything about it. It has a Wico XH mag if that helps. Any info or value thoughts would be great.

Randy

Randy,
Here is the little information I was able to find quickly on your Wisconsin BKN:
Bore & Stroke: 2-7/8" x 2-3/4"
HP: 7.0 @ 3600
Introduced: 1955

Since your motor looks to be complete and has a gear reduction unit on it, if it turns through and has compression & spark (or the mag impluse at least snaps) then it is definately worth putting a little effort into. Wouldn't know an accurate dollar value to tell you, but if I saw it for sale and it met the above requirements, I would go up to maybe $80 for it.
Free advice is worth just that!

7 hp!!! Wow - I would have thought a lot less; however, I know more about the hit and miss type - so thanks for the info.

How many years were these produced for?

It does have great compression and the impluse works just fine. I don't know if this engine saw much work??? What would it have been used on?

ASECC has a page on this design. I have several older versions. They are all about the same design, which Wisconsin made from the late 1930s for decades after.
The Feb 2002 Gas Engine Magazine has a story with some pics.
As for what it was used on, could be anything.

Randy,you did a great thing rescuing that beast from the dumpster.That's just too nice of an engine to let go.Looks like the only thing missing is the fuel sediment bowl.If it's a school board engine,it most likely has VERY low hours on it and should run great.I have two wisconsins myself,an ACN and AKN,both made in the mid 50's.Good luck!

Scott

Finally wrote down the serial number - 3854086. Any thoughts on the year based on this??? Also, where could I get a proper sized sediment bowl for it?

Thanks,

Randy

Sediment bowls are pretty easy to get. If you have a Tractor Supply in your area, or a store of that sort, chances are that they'll have one for you.
