I have an 11 assault in surgery and looking with a mirror at the jam nut on the pump arm and looking centre on the bolt I see no slotted path for a straight edge screwdriver only what appears to be a round hole? I blasted it out with brake clean looking closer for alanhead or torques shape but it's not clear to me. I watched YouTube clips of turning up 12 and newer pro,s but what do I need to know about turning up the pump a bit on an 11 assault?
Cylinders off reeds are out I thought this was going to be easy to turn up the oil pump lol
