did you make sure the chain was tight on the drivers side?? right side as your looking at the engine?
this is very important 2* off can be a big issue.
Do you mean when installing the cam sprocket on the chain? I don't know if he did or not. I do know the cam pin is lined up correctly with the arrow on the rocker arm with 0TDC on the crank.
The LC adjustable cam gear has been retarted 2 degrees by him due to the decking and head blocking issue. He said it didn't make much difference from straight 0
Getting a dual row adjustable cam gear on the cam is a PITA! I am not sure I could do it keeping the chain tight on the right side.
could you explain the chain issue in depth???
