I've also got two of those NOS:thumbsup:
That engine on eBay is a BELSAW engine.
BELSAW is like a vocational school that gives a student a motor to tear down and see how they work. Look at the pictures, it looks like that motor has been apart.
When I was in high school we had a similar class, we were given a Briggs to tear down and reassemble, then we had to start it and make sure it worked.
I recently scored four NOS Briggs 3hp motors from the local high school, and they were all brand new, but taken apart and (poorly) put back together. :doah: These never ran. Connecting rods backwards, busted bolts in the block, ALL of the pistons and rings are junk, I don't think they had a ring compressor and just beat the pistons into the blocks. The float style carbs were all messed with too, clocked wrong, missing parts etc. A couple of the coils were mounted backwards, they used the sump cover bolts in the rods, the list goes on and on. Basically these motors I got were just good for some parts, even though they were essentially brand new.
I would be real careful shelling out anything for that one on ebay, could be a BIG gamble. Especially considering what the last two sold for.
