LGM-1 compression stroke adjustment - how should it be?

[Paul G.]

On an LGM-1 (or perhaps LGM-2), can anyone tell me if there is an adustment specification for the position of the piston as the piston reaches it's closed position (as the cocking arm is closed)?

There is an ecentric shaft that can be rotated to adjust the piston displacement (closed position). I would like to know the design intent so I can set it accordingly.

Thanks,

Paul
