If you see fuel weep out the threads as your removing the plug its too high, tighten it back up and lower the float height. And try again.

Think of nothing else. Check and set rear float also while engine is running.

Welp....
I guess the leakdown test was probably moot.
Unless this could be from the 'decorbinizing' treatment I did.....

Please tell me that is NOT the first time you have removed the oil-fill cap........
That can also be from short trips, in that the engine doesn't get hot enough, for long enough, to 'cook' off the water from condensation that's inside the block.
Is the crankcase over filled now?
Have you run a pressure ck on the cooling system?

Definitely NOT the first time! That's why I was floored...

And short trips would explain it...
I've only been driving a few blocks during this 'project' to test for knocking.

Haven't tested the cooling system pressure because the PO pushed it into the fan at some point and there is sum kind of bubble gum crap on there, i assume to plug some leaks...

I must have screwed up the leakdown somehow.

Every cylinder showed 100% leakage, with air escaping in various areas.

So idk....

Sure you were on the compression stroke?

With 170# of pressure it can't be leaking that bad...

I used my compression gauge (minus the needle valve) to find the compression stroke of #1 cylinder, then verified TDC with the 'screwdriver' method.

Then went along in firing order verifying TDC with the screwdriver as I went.

I just don't get it.....

Just for S&G’s, below is where I noted the air passing through the engine, per cylinder.
Maybe this indicates where I went wrong. Maybe not.

The one that really seems odd (to me anyway)is #2 leaking into #1 cylinder.

Cylinder/ Leakage Location

#1 Oil Fill
#2 #1 Cylinder
#3 Oil Fill
#4 Oil Fill AND Exhaust
#5 Intake (carburetor)
#6 Exhaust
