Bypass the filters and you will probably solve the problem. I put an inline filter on my Roadster and could never get it to run right. Removed the filter and never had another problem. Modern filters don't do well with gravity feed systems, and with two of them you are doubling the problem.

Wingski the glass fuel bowl should be full of fuel not half full of air as in your pic. Loosen a union nut after the bowl to let the air bleed out and the bowl should fill. Then test the fuel flow after each of the filters and see if it is a full pipe-diameter flow into a catch can rather than a piddle into a catch can.
Those filters may be restricting the flow and causing lean running.
If the glass bowl will not fill when the top union is loose, then there is a blockage between the tank and the bowl.
We recently found an earwig in the fuel tap in a car! Each time I blew the pipe clear the earwig shot back up into the tank and then re-dived head first into the tap again after a few miles. The bowl had a partial vacuum and air in it as a tell-tale of the blockage.
In your case it is likely the filters will not flow enough under gravity feed without a pump.

By the way you have a nice looking engine set up to my old eyes

If you're getting fuel past the glass bowl I would take the nut loose on the bottom of the tillys to see if the fuel is making it that far if it don't pour out at a good rate it could be the jet clogged in the bottom of the bowl or a float or needle valve issue but if you are getting good flow then your main jet could be clogged, just a couple of thoughts, I had the same issu, I put an inline filter and where my tank is rusty rust particles would stop up the line from the tank to the filter, poped l the filter off turned the valve on and let it flush the line out pop it back together and fired right up

Wingski,
"Somebody" did some IMPRESSIVE looking work! I can see why you DON'T want to go back to STOCK!
I "wonder" if the manifold was painted with Cast Blast? I've heard it works well for HOT manifolds.

Fuel line to the front carb. looks to rise a bit before it heads downward to the float bowl. Remove the filter ( both of them) and the fuel lines will head downward and not trap air in the high spots which stops the flow. How do you expect to balance the airflow through the dual carbs, the exhaust is in the way. That's the first step in setting up the carbs. so one isn't rich and the other is lean while it idles on only one?

You were right. The inline filters were not made for gravity feed. Thanks, Mike

I removed both filter elements from the holders. I'll start it up when it warms up a little outside. Thanks!

I am also thinking fuel and fuel filters. Was on a tour with our club and one car was having similar issues as you did. After gong through a lot of things because "it could not be a fuel issue, the filter is clean.. see?"
Long story short, took the filter off and viola, ran fine. Just to rule that out, bypass the filters and see if it runs.

I agree that vapor lock may be the issue. steroids for sale Fuel filters clogged are also an easy thing to check as well as a tight connection along the exhaust system from manifold gasket to the tail pipe opening.

Check the gas cap vent hole. Remove the gas cap and see if it runs better.
No inline filters. Look inside the gas tank and see the small filter there.
