o[ I kinda feel like that just now. Got a really pretty rebuilt ThermoQuad from a well known rebuilder,
but canNOT seem to get it to idle properly. The engine "surges", racing then falling off - about once per second.
I've been assuming a vacuum leak, but can't find one with the rubber hose "stethoscope" trick. Tried just starting
over, resetting the idle mixture screws to 1.5, 2,and2.5 turns out from the seats, but can't seem to find a sweet
spot. if I adjust the curb idle screw to raise the idle speed, I can make it whistle like on old Navy bosun's pipe,
but have to crank it up to where the surge is almost 1500rpm so it doesn't die in between when it warms up.
Any ThermoQuad experts out there
