make sure you have a good set of points and condensor, rotor and cap etc. if it still does it, do a the leakdown test. that will tell youif you havea leaky valve. may be just a weak valve spring as well. especially if it sat all that time without turning over. also, just for giggles, try running it at night at operating temp, with the hood open. see if it misfires from one plug wire to another. oh, by the way, if you are gonna take a plug wire off one at a time with it running, take the wire off at the distributor end-less chance you will get zapped! it does sound like it is a little low on compression at 110.
good luck
