Hamada 665 impression problem

[splashdesignz]

My 2 color Hamada 665 is having an impression problem. It seems that the detent pawl has really gotten out of whack. It will not consistently engage the impression during a job. It might impress on 2 sheets then miss 4 then impress on 20 then miss 1. I have tried many different things all to no avail. I know that there are some guidelines for the settings as to where the latch should be set and the pawl but I do not have access to a service manual and I am 200 miles from the nearest tech. I'm wondering if anyone would have this info or any ideas for how to solve this problem.

Thank you very much!
