Default Help setting up OS Max FP 40
Bill,

If your O.S. Max .40 FP has had a bunch of running on it, it may have a worn piston/cylinder fit. When the compression starts to go, the idle's the first thing to go bad.

If the engine's new, it may not have enough breakin time.

The manual for the .40 LA will have the same adjustment and breakin procedudres, and you can download it from:
