Hi, Could anyone let me know the gap setting for the piolet valve control arm assembly on the spool motor, part numbers 200 and 201 of attached. We have bought a second hand irrigator that have been overhauled, and have found the inlet and exhaust hoses connected the wrong way around and a gasket put in upside down. The manual says not to dismantle as it's been factory set, but no instruction as to what the distance between the two striker faces should be. The irrigator is also called a Rodney Industries RI30
