are you getting up to temp.i know my dom,s a real cold natured.but once up to temp they run and idle good.

Does anybody got any more ideas? I took the carb apart and blowed through all the passages in the metering blocks and main body and put it back on and it still will not run unless you keep patting on the gas.It will run for 4 or 5 seconds and die unless you pat the gas. It will crank back up and do the same thing.I also kept doing it until it got up to 160 degrees to make sure that was not the problem.
It is a ProSystem 1050. Looks like I will have to put the 950 back on to race tomorrow. I was wanting to see how much ET it would pick up with the Dominator on it.

Not that this is the case but I have seen some gaskets with really poor hole placement that blocks of large portions of the feed holes in the metering blocks.
Best way to tell if you have a 2 or 3 circuit carb is the 3 circuit will have 3 air bleeds above each venturi and the 2 circuit will have 2.

For reference here's what a 3 circuit gasket should look like

Are these the correct gaskets?

Another pic.

Yes they have the correct holes

Place the metering block gasket on the metering block and see if they line up correctly then do the same with the gasket on the main body.
This way you'll be sure the hole placement is correct.

Also check the main body and metering block for flatness with a straight edge to eliminate dealing with a warped component issue. This can cause the circuits to cross feed and really throw the tune/adjust-ability off.

Make sure your power valve and power valve plugs are tight and the gasket is in good shape.

For checking the small passages in the carb I've found taking a piece of stranded automotive wire about 3-4" long, slit the insulation lengthwise and use a strand of wire to probe into all the passages has really helped me locate and free a plugged circuit on small motorcycle carbs

Your going to have to look at every circuit front to back, top to bottom for the issue.

Here is an example of a gasket with bad hole placement
