The 1050 dominator on my 460 is acting up. It worked perfectly all last season. I rebuild it again this spring with a quick fuel rebuild kit, used the same jets and everything as last year.
So far this year the engine starts good cold and will start good hot if you shut if off and then re start within a few seconds. But if you let it sit 5 minutes and try to start engine it will be very flooded. Plus the floats will be almost empty. The gas is draining out of the float bowls into the engine with the key and the fuel pump off. So you have to hold the throttle wide open and crank for a while to get engine re started. It also smells too rich at low rpm but runs great from 3700 to 5400 rpm. It will sit and idle for as long as necessary but smell rich.
None of these things were happening last year so I know its not a jetting issue. The power valves are blocked off but I tried replacing the power valve gaskets again thinkng maybe the gas was leaking through there but that didnt change anything. Also verified that the bowl vents are not clogged by blowing through them wich resulted in gas spaying into the throttle bores.
Im running a holley black fuel pump and a quick fuel bypass regulator with 1/2" id fuel line. Last year I had a holley blue with a dead head regulator and 3/8" line. I run about 6psi fuel pressure. 93 octane pump gas.
