That check valve is there to prevent fuel from being siphoned out of the shooters at higher rpms. Seems to fit your symptoms quite well.

It’s all fun til the rabbit gets the gun.
This week I made the following changes:
-replaced 5/16” fuel line with 3/8”, installed new fuel tank sender, hp fuel pump, and mopar vapor breaker with 1/4” return line.
-removed blue pump cam and installed a much smaller green cam.
-replaced 160* thermostat with 180*.
-Lowered rear float in carb.
-Checked front float, needle and seat and were all good.
-minor carb tuning tweaks.
-adjusted pump lever arm spring.
Test drive this morning was perfect. No flooding or stalling up to 75mph. It’s only 48* this morning, so we’ll see how it does driving home when it’s 75*.
I’m hoping the monster blue pump cam was the issue. The other changes were ones I just wanted to do anyway. I believe it’s happier in general at 180* as well.
