When I install my Gauge in the adapter and tighten the set Screws the gauge
binds, I have to turn the Engine backwards and then push on the top of the
Gauge to get the adapter to follow the Plunger. Turn Engine a small amount
and push the Gauge to follow.

IT might run if all else was perfect, but I doubt it'd run well and you'd
probably have to tow it. If the gauge isn't moving when you run the
engine back, either something's hanging in the distributor since you put
the o-ring back in or something's binding in your gauge not letting it
Just talked Dad half through a top cap re-seal on a CAV pump on
one of the tractors. He said the shaft o-rings were the worst ones
he could ever remember installing! Really had to stretch them over
the shaft and then the bottom on had to go past two other grooves
to get into its own. Once primed it started, ran and shut off! :-)
That's the only stuff that was disturbed so it was a success!
