It just goes to show you, always get back to basics. For all of you that have helped me in the "surge" / "miss" problem I was chasing,,, I finally got the answer this weekend.
After trying multiple combinations of jetting I still had the miss. So I went back to basics, pulled the distributor and meticulously went through it. I found the points plate was worn and had a significant wobble to it. Enough that the dwell was probably fluctuating and the points inaccurate when it was running. I pulled out the original distributor that came with the car, checked everything, cleaned it up, reassembled it with new points and condensor popped it in, set the dwell and timing... I also made a slight adjustment to the choke and limited the travel so it didn't open to a 90 degree state when warm, maybe 75 degrees or so and presto! Runs like a charm, pulls strong and cruises like a brand new car. Ended up with 073 jets and 041 rods, B secondary hanger and CE rods. Put 80 miles on it yesterday, AND took second place in a POCI sponsered local all Pontiac show! All in all a great weekend! Don |

Thanks Bob
I still think there is something wrong... Shouldn't the primary choke plate be wide open when warm? Once I closed mine down it smoothed right out, vacume became rock steady at 11 inches and it gained about 100 RPM. I am going to send the carb out to have it professionally done, probably in January. I can discuss the details with the shop. Maybe there is some junk restricting the gas flow at idle making it artificially lean... Don |

My guess is that you are lean for some reason. Vacuum leak?
