Compression check, etc...

Today Lou and I did a compression check and then I re-checked the fuel levels in the carburetor bowls.  We also re-checked the intakes for leaks and confirmed that they are still leaking.  I have a new set of intake boots from Z1 Enterprises which I will install very soon.
The engine passed the compression test with 177-195 psi in all four cylinders.  Number 1 had 195 psi and the rest were between 177 and 187, if my memory serves correctly.  Lou took his notes with when he left, probably because he was afraid they would get lost in my garage.

Carb 1
Carb 2
Carb 3
Carb 4
I used a lawnmower gas tank to run the engine for warming up prior to the compression check.
Cylinders 3 and 4 had a better intake seal and are badly carbon-fouled because our jetting is too rich.
