Unexpected surging
Today it snowed all day in N/W Pennsylvania. Yesterday it was 72* and sunny, a perfect day for an end of year romp in the "75. I left at noon and toured the country side in PA and Ohio with every turn adding another 15 minutes to my outing. The recent build on my Qjet was working flawlessly and in combination with my new distributor has eliminated the surging I had been fighting all summer. I was banging gears and grinning for 3 full hours. At the end of my trip I stopped at my local fill em up station and topped off the tank with 91 octane non ethanol and a half pint of Sta-Bil to get ready for the long winter. Even before I left the lot the car was bucking like a green pony. If I had been a couple of miles down the road I would say it is bad gas but I was just pulling away from the pump when it happened. My trip home was about 10 miles and by the time I got home the surging was not as bad as at the station but still there. Could my intake and carb have heated up enough to cause the problem while sitting without the engine running or should I look somewhere else? It was definitely not the end I was hoping for on my last ride of the year. Any ideas are welcome, Thanks in advance.

woulda p'd me off about the time you really start thinking "Now Im on top of it!"
At least its not a code that some shop will bang you for a grand only to have the light come back on.
So it did the same thing before the rebuild just not up until this last drive? Is your connection to your HEI? condition of plug wires, sometimes one thats arcing a bit or a bad plug can drive you nuts.
Does it do it in N or with no load on it, at steady cruise or under load?
