Hey Kip, thanks for info. I see the notches you are talking about, but didn't think the hole lined up with 'em. Well, it idles really well and starts really well. But when i go from idle to wide open throttle, it stumbles and sputters through the carb. Sounds like timing, but I checked the timing and got it spot on. So i'm not real sure where to go next! When I hit the gas, the vacuum advance turns the distributor so i'm assuming thats working. If I slowly give it gas it doesn't do it, just when I snap it. What do ya guys think? Thanks.

a 30,000 mile UNMOLESTED original, now my daily driver! Original 6 cylinder with a rebuilt '66-'69 Saginaw 3-speed Overdrive. Synchro low! Otherwise, everything original down to the spare tire. Interior is like new. Needs paint, but absolutely zero rust.
