977 Regency 98, Olds 350, TH350.
Start car, let it idle a minute or so and pull out driveway... Then almost every time, on next accelleration after stop sign (one block) car bogs and dies, and won't restart. If I fully warm up car in driveway, all is OK.
Noticed no fuel when accellerator pumps at carb a few times after car dies, so last nite I tried to not "panic pump" the pedal when it died. There WAS some fuel in pump then. However the ONLY thing that will get it to run and continue as normal is to put some raw gas down the primary of the carb! It fires up immediately.
I know the Rochester floats can't be adjusted "on the car" and have Gumouted this thing inside and out, and still it seems to be a fuel starvation issue. I have not "dug" into it for it always dies on the road, but pouring a Testor's model paint bottle volume of gas ALWAYS works, and I can't get it to "die" again after that.
Maybe a vacuum problem that thermally corrects itself? I have NEVER had such a repeatable and bizarre problem in 25 years of working on cars....
Replaced fuel pump, fuel filter, plugs, wires, cap, rotor, adjusted choke, checked linkages, vacuum hoses, tightened up loose bolts at on carb, and blew out fuel lines, as well as all other "maintenance" items. Car is in VGC, and other than that it has no problems.
Any ideas????? Thanks!
