10psi is definitely in spec, that however was between the highest pressure and the next highest. here are my results averaged over 5 tests.
#1 205 #2 165
#3 190 #4 205
#5 205 #6 195
#7 215 #8 180
The manual says that the compression pressure should be between 200 and 225 psi, and calls for a variation of 25% max between highest and lowest and if my math is correct the minimum allowance would be 161psi for the lowest pressure. However a 50psi variation seems like it should be out of specs. The numbers on the left side of the engine seem respectable, but the issue is definitely on the right side. I saw the crack in #2, but #4 fills up with water when the engine runs, so I don't know exactly what the engine issue is. Fortunately, I have a replacement ready to go in.
