the gt will run fine around town, no problems there. it has smooth acceleration under almost all cases, but when i romp on it from a stop and take it through like 1st and 2nd directly after there will be bucking and a loss of power. its almost like i took my foot of the gas. it going away after about 30 sec's and if i give it more gas right after it starts then it wont buck....
i dont know what it could be because it runs really strong when your on it. i could run it all the way through 4th with out a loss.
any help is greatly appriciated.

Rebuilt carb don't really have nothing to do with the fuel filter. Was the filter replaced at the carb rebuild?

Bump! Same Issue here! I assume the fuel pump isn't holding pressure when shifting gears. Bad check valve on fuel pump? Its definitely fuel related I believe.

#1 I think this is a carb swap (does not matter, see #2)
#2 this thread is 15 years old.
look for a date stamp in the top left corner of a post
most don't notice it so they talk to ghosts
