thanks for the responses fellas!
popped the cap off the dist and sprayed a little pb blaster on the advance springs and down in there, worked it till it seemed to spring back quicker and smoother... it was going pretty slow before and not returning completely. then adjusted the idle down to 800rpm and did a little four corner idle adjustment and timed it to about 11 btdc which seemed the best.warm idle is now roughly 800rpm and about 700rpm in drive.
doesn't seem to stumble as bad or often, maybe i've just gotten used to it lol. when i ran it up to around 1000rpm it started to advance slightly with the vac advance unplugged. does that sound like too quick of an advance?
also noticed the timing reflects the stumble... seems to retard about 1/16 of an inch at the time of stumble/hesitation. now when i rev and drop back down to idle it doesn't seem to hesitate like it did?
i'm going back and forth carb or dist, both were used but the demon was in operation for a limited time by my brother then sat for a couple years and the dist was an ebay buy history unknown
my plugs have gotten pretty dark with all the adjustments so i think i'll head out to grab some new ngk 3332 plugs.
here is a quick video... does she sound a little better?
