OK guys, my `96 SLT 780 runs great after 2800 rpms. At idle I have to choke and flutter the gas for it to take off. I took the carbs apart and cleaned them but did not change diaphrams as thet looked good. Fuel pump, shutoff valve, compression are all good. Since it revs up to 6400 rpms and has as much top end power as when new I would not think I have a fuel delivery problem, but can the fuel pump be bad down low and then good on top? BTW mt popoffs are 19, 21 and 21, thanks Mike
