Cylinder 1: 127 2: 127 3: 125 4: 110 5: 127 6: 140.
8.2 8.2 8. 7.7 8.2 9.5
Cylinder 4 and 6 were tested twice.

I think 8.2 is about right? cylinder 4 is a little low but 6 seems really high

any thoughts

was that a cold or hot motor test ? you should get higher readings on a hot motor test, as long as figures are with in 20 psi of each other it should be good.

Cheers Chris

all on a cold motor,
