Just won't idle
Need help, fully rebuilt 351, 302 rods, 302 heads, 35/75 solid cam. edelbrock performer, a set of rollers, hi-6 ignition, and a 600 vac sec holley. Fires straight up then dies, runs great above 2000rpm, crisp and clean, anything less and it dies as if you turned it off, have cleaned and kitted the carby, paying particular attention to the idle curcuits. I am confident that i don't have any vaccuum leaks, at a losss, can anyone help.
