i have a '75 350 in my carmaro, and i rebuilt the carb, it was working good but today i started it and when i step on it in all rpm ranges it boggs. it doesn't go and then bogg it just boggs.
if i hit it to hard off the line it will stall out.
my timing is at 13 degrees btc. seems to be the best place for it. tell me if i am wrong

Bidn't mention your carb type but.... accelerator pump is screwed up probably. Look down the primary venturis (engine off). Open the throttle quickly by hand. you should see two little streams of gas shoot out and actually spray onto the little booster venturis. If you don't see the streams or they are weak or broken you've got your culprit.

Grandma's old 78 Malibu (33K miles!) soon to have the powertrain from the 79 put in it.
