Cylinder Compression Issue
 
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 01-14-2011 11:26 AM
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
