I have an 88 GW 360 that I am installing a Carter AFB 625. Does the GW use a timed vacuum advance port or not? Any help would be appreciated.

Vac adv runs off both manifold vac and ported vac.
At start up it draws manifold vac via a CTO switch for smoothing warm up. At 165*F or so the CTO switches the vac source over to ported vacuum.
