Default popping noise

Hello everyone,
Just recently finished my 29 speedster. I have noticed a continuous popping noise then the engine dies. I have a model B distributor and a tilitson carb. Having trouble finding the problem could use some help.

Thanks,
Jim M

Could be fuel starvation. Check the easiest things first. Is the gas cap vent working? If so, check for clogs in the gas line.

Next time it dies, stick your finger in the carb near the choke blade and see if it is wet with gas. Bet it comes out dry.

When the engine died, checked choke blade. Dry as a bone. Removed the gas line going to carb at first a trickle then stops, then flows more steady.
Something in the tank? Newly lined tank?

What was used to "line" the tank?? Was it Ethanol proof?? Do you have the "pencil" filter installed in the tank??

I removed a small piece in the gas line near the sediment glass bowl. checked gas flow slow at first. turned the choke adjustment 3/4 to the left. It runs good now. adjusted idle down.
I think it's ok now. The pencil filter was not installed. I better install it.

thank you for your help/ could be frustrating.
