OK, that hole you are pointing out is in the cylinder head, so that is not the bleed hole I am referring to. Steve kindly posted pictures of the hole I am talking about. This hole just bleeds off a little water to help keep the exhaust housing cool, but it often gets plugged/blocked by carbon…
So cool, great work indeed!

Larry, I wasn’t planning on using plastigauge I’m just using the better of the two cranks. They did make oversized pistons for the qd 16 but the bosses could wallow out again over time which is why I wanted the upgraded pistons/rods from the qd 22 in hopes my kids never have to split the case again😉
If you haven’t I’d post a wanted to buy on this site. I’m sure someone here would have a good used one they could part with. I have been helped out many times by this great community.
You can’t use plastic gage on this engine because the rods have needle bearings. The little 5.5hp has plain bearings, so plastic gage can be used, unfortunately there are no specs to go by for its use though

Nice job – good to see the swap-out worked.
