You really can’t confirm if the case gasket is leaking as you can’t get in between there.
Once I get it together, before I reassemble anything else, I’ll do another pressure/vacuum test. If it’s good then I’ll put it back together all the way.

You can't see it from the bottom and front of the saw? My memory must be fuzzy here.
Not really. You can kind of see in there but not very good. The seal is hard to see too. You cant see at all on the right side by the gas tank, no way to really see in there.
Got the crankcase halves back together today. Put some oil on the crankshaft and the recessed area where the bearing fits. Also put some on the bearing itself.
Put some motoseal on the mating surfaces and slid the gasket in place. Fit the case half over the crankshaft and slid the crank seal slowly over the shaft. Got that seated good and then tapped the case half on with a wood block and hammer. Got it seated good and once the studs stuck through the case I put the nuts on and tightened it in a crisscross pattern. Got it tightened down pretty good.
Had to tap the crankshaft a few times to free it up. It spins nice and free now.
Brought the saw inside so the sealant could cure at room temperature. It’ll get down to 20-30 degrees at night out in the garage.
The gasket sealant package said to let it cure for 24 hours. I’ll wait to do a pressure test until tomorrow or Wednesday.
Hope it sealed up!
