Recently, my Holley 4160 carb started leaking with some older gaskets so I rebuilt it with the blue gaskets, soaked it and had every part out on the table. I set the float per specific measurements and all that. So when I put it back on the 440 and set the idle screws (backed out 1 1/2 turns), it is having problems running. I need to fine tune it and set the timing but I don't have all the "factoids" to do it I watched some videos, but its not that easy.
It starts great when cold on the first couple attempts every time. However, once it warms up, it stalls on its own. The idle does not settle down with a pump of the throttle. Also, it is too rich as it starts fine, but gets richer each minute. Then it will have trouble starting and even backfire. New plugs, new wires, new fuel, new distributor but not sure about choke adjustment, idle screws and the order I should be making each adjustment. Can't take it out for a drive like this so I was checking with the best by getting on here.
