My father in-law picked up this treasure at an auction a few years back.

It's been sitting since along the back fence row getting swallowed up by the weeds until we started clearing off the fences again & drug it to my shop.

I think he got caught up in the bidding & paid way to much for it, but I told him it's not a total loss & I could bring it back.....with a lot of parts!

Unless I can find a correct Briggs for it, I'll probably throw in a spare K181 I have on the shelf.

Currently in the process of tearing it down,my FIL will paint the tins while I do the mechanical work.

Check out the inspection window on the backside of the engine!

I don't know what to say Stephen.  Biding on that, he must have had some idea of what to do.    You've got another one for parts, don't you??

He didn't see the hole in the block till after the fact.

And he's not aware of what Horse's are worth more or built better.

Yep.

 

I think the hole is for checking the rod cab bolts, then you just put a new band aid over the hole & back at it.

A new rod and a couple tubes of JB Weld and it will be good as new!

Easy add oil filling that's fer sure. Might have been hidden in by the starter?
