i just put a new power valve in it, i even called holley to make sure i had the right one, and to make sure i had the right jet sizes, which i do, it is a 3310 750 vac. secondaries, 6.5 power valve, and 74s in the front 77s in the back, 7 psi of fuel press. and have set floats properly, proper gaskets and made sure it was clean
im stumped the only other thing i can figure is ignition, could this be the issue, maybe not gettin enough spark
because today it would idle for like a minute before it would start sputterin and poppin through the exhaust, and smoke too,
