I forget how large the pivot pin is? Is is large enough to substitute a smaller pin and just add offset drilled bushings?

I like extending the cone or adding profile on top of the MP for and easier way to increases travel.

The Andial Fueler and BL's modified WUR both lower control pressure so the metering plate will advance further. This indicates it dose not bottom out on most 930's so adding range by blueprinting the casting is not of much benefit if the arm is going to stall any way.

Again, I suspect one relatively easy test to see if it still has range left is to set the CO as fat as possible at idle and run it up to red line watching AFR at a peak rpm point like 6600rpm. If this helps the AFR, then the pin has not bottomed out. If the AFR stays the same, the pin may have bottomed out.
