Cylinder Compression Issue

[pemz0r]

Old cylinders and new pistons. Cylinders 1, 2, 3 have exactly 50% less compression than cylinders 4, 5, 6. Could the valves be adjusted wrong or is the cam timing off.... or any ideas?

Did you open your throttles to the other side>?

[pemz0r]

yea they are open.

#1 85psi

#2 57psi

#3 57psi

#4 115psi

#5 118psi

#6 116psi

Haven't looked at the valves yet, so I am hoping that is the issue

double checked the throttles....closed.

that solved the problem, thx
