I rebuilt the carb as I was having hard starts - I'd have to pump the gas pedal and even crack the throttle open to start the car, and upon hard acceleration there was a noticeable delay.
Nope, no way to keep the car running without mashing the gas to the floor. 4160 does have two sight ports, but I can't seem to tell if the floats are level with the carb bolted in, how do you do this? Even with a mirror and lighting it looks (looks) like the float in front is slightly high, and the one in rear slightly lower.
It actually "puffs" fuel back out of the carb after I try starting it now. I didn't do any other changes to the car, just the rebuild, and the filter is not even a year old. Carb body, metering block, and the empty float bowls were bathed overnight in thinner, scrubbed, and blew clean.
I looked at the old gaskets lat night, they have locating holes to prevent them from being installed backwards, so I honestly don't think I could have installed something backwards.
I just can't believe I'm so far off. She won't even start now, just spins and puffs out the carb, as if to spite me.
