Great to hear! Good work.
Keep an eye on oil usage until you figure out whether it is or isn't using oil
heavily.

Thanks to everyone! The Atomic 4 is revived! Have run it for a couple hours now and everything seems great! New alternator, new electric fuel pump, new fuel lines, cleaned out the carb two more times. Moving water well, temps are good and it shifts well ????

All normal installations have a fuel pump managing the fuel flow, rather than relying on gravity only. I've had success with a manual fuel pump, but electric fuel pumps are becoming more common. They are not expensive and simple to install. Alternatively, if you squeeze the priming bulb every couple of seconds maybe you can "be the fuel pump" for testing purposes.
The Zenith carbs use the floats in the carburetor to control the inlet control valve. The Carb bowl fills with gas until the floats shut off the flow, and provides several seconds of running time before call for more fuel.
good luck on your project.

I'm not sure about the fuel pump comments. I will describe how I was attempting to get fuel to the carb. I used a portable fuel tank sitting on the cockpit seat with a fuel line that included a priming bulb and a fuel filter. feeding directly to the carb. Pumped up the line and figured it would be gravity fed. I cleaned out every orafice I could on the carb. Am I missing something? It did start initially right away ran for a few seconds and died. I did not use any starting fluid on that initial start. I'm hoping to get it fully running this coming weekend so I can assess the cooling system. I'm thinking the carb may have plugged up from something in the line. And planned on cleaning it again, But would like any advice I can get.
Thanks to everyone!

I'm getting closer! Got the stuck valve unstuck, compression is now roughly 90 in all four cylinders. Cleaned out the carb once and it fired right up and ran beautifully for about 10 seconds then died... Then could only start and run with starting fluid. I'm thinking even though I am using good gas in a temporary tank, something must have made its way in and clogged it up somewhere... Will clean it again... Is there supposed to be a spring or a wire holding in the inlet valve with the float? If there is it is missing. I also need a new alternator. Any good options out there? Then I need to sort out the fuel line, pump, filters and valves. Here is a quick video of it starting with starter fluid.
