Wait, I made a mistake.

There IS vacuum supplied at idle.

This makes the total maximumtiming under boost 10 (static) + 0 (vacuum or boost) + 12 centrifugal = 22 MAXIMUM.

This distributor has the control arm attached to the left, which allows for vacuum retard. Most US distributors have the control arm attached to the right (see diagram below).

The correct timing for this distributor is 0 + or - 2 degrees AT 1000 RPM with the hose connected.

The maximum timing under boost is 2 (static) + 0 (vacuum or boost) + 12 centrifugal = 14 crank degrees.

UNDER NO CIRCUMSTANCES SHOULD THIS DISTRIBUTOR EVER BE TIMED OR "LOCKED DOWN" TO 26 DEGREES AT 4000 RPM. THIS WILL BE THE TIMING YOU HAVE UNDER BOOST!!!!
