Re: Waking up the ZZ
pdawg, set your total @ 32,(2800 -3000 rpms) with the can unhooked & plugged (as you know). Then hook up the vac can & read what you have....if you added 12 degrees on the can, you will read @ 44 degrees @ 3000 , with no load in the engine. This is ok , as the vac drops when you open the throttle & you are only running on initial+ mechanical @ WOT  The vac advance is for cruse& economy on a 'slow burn" (part throttle). The vac can is NOT considered as part of the total timing....just a load compensator  longhorn
