Home rebuilt 1920 has poor accel shot

I disassembled the carb and found the problem. The accelerator pump diaphragm/gasket was slightly misaligned but still lining up with the screw holes. the misalignment caused a partial coverage of the port that the accelerator pump would pass fuel through.

I did drill out the two clean out plugs and clean the check weight and check ball. Then replaced the plugs with the supplied from the kit.

I made a little gasket shim to hold the gasket in the correct location while reassembling the metering block.

Accel pump now works excellent but unfortunately I now have a high idle. When hot.

So I'm assuming either when I replaced the plugs they are not fully sealed or whenI made the little shim for the gasket It is holding a metering block up so it's not fully against the diaphragm / gasket.

Good news is drivability is back. I think what I'm going to do is get some spare screws and cut the heads off. use them to align the gasket so I could drop the metering block into place without the silly little shim. Then reassemble after JB welding over the clean out plugs that were replaced.

I hate old carbs
