Very frustrated with D-engine mower

I once use a hardware pressure gauge rigged up for a Husky chainsaw motor that was acting up. I think the drill is like a compression reading . Take the reading and see if it holds.
Wish I had bought a Yamaha 350 and kept it. (trivia)
 
Another thing to check is if you installed the reeds correctly. The reed must be installed with the rough edge away from the machined surface on the reed plate. It also has to have a .015" gap when installed. The reed evidently has a rough edge and a smooth edge.

Its all fixed now.

After all the rebuilding, the "MAIN" issue was the carb primer was not working, thus it wouldn't start. I put in a "kit" of primer parts, it primes well now, and it starts easy when cold. I did take another compression reading after the mower had been setting for four days, and I got about 68 lbs max, after several pulls, so I am within spec. (D-400 engines are supposed to have min. of 65 lbs).
