bogging 318

If you move the throttle open a little how much vacuum does it pull then? The port you are using is mostly blocked off with the throttle closed. 15 in hg = about 50 kPa. No load needed to set base timing "by the book" I don't use base timing but rather total mechanical advance. No vacuum hooked up set timing to 28-30 degrees at 3000 rpm. (most distributors stop advancing at or below 3k rpm) A good timing light with dial back capability is nice for this. Having not owned on yet (why I can not tell you as much as I tinker with this) I set my timing mark at 10 degrees btdc and make a mark at 0 degrees. Then move this mark to 10 btdc and make another mark a 0. now you have 20 degrees marked and 10 or more on the engine engine tab. Gets you close to 30 and you can fine tune from there. Add vacuum advance after total is set and you are satisfied there is no ping at WOT throughout the RPM range. Some vacuum advance cans with a hex shape near the vacuum port can be adjusted also. As for the bog, does it come back to life after letting off the gas or just die out? Will it eventually gather itself back up and take off? Does pumping the pedal while accelerating help or make it worse? Also check you Alternator output. Literally just had this happen with a failed battery and alternator yesterday.
