Ok so I followed everyone inputs on this 5 HP Briggs.
My brother took it to his shop.
He machined the bore and inserted a fresh cast iron sleeve.
He put a nice cross hatch pattern on the sleeve.
He decked the mating surfaces on the block and the head.
I purchased a new head gasket.
He polished out the piston on the top and skirt.
I also purchased new standard. ring set for it.
He also polished the lifters.
He even dressed, cleaned and polished the intake and exhaust valves.
Then he finished it off by lapping in the valves.
All in all I guess it can be said this is a new block.
With all that work having been done when I reassembled the Briggs.
There was no change in performance other then it starts on 2 pulls on the rope.
So for the second time I had to break a primary rule I learned in H.S. power mechanics class.
That rule was NEVER EVER BREAK OPEN AN ENGINE unless you are sure you need to.
So after sacrificing another running engine I made this video now I am sure my carburetor is shot.
Also Lady Sentinel did an extremely extensive examination of the main jet.
She broke the bad news to me, she said there were striations wrapping helically around the inside of the main jet.
Oh crap the carburetor has been drilled out.
So if you are still awake and have an interest hit the video.

I wish I could say no engines were harmed in the making of this video.
But I doubt I can.
