The heat riser clang...

My original Carter carb hasn't had choke butterflies, nor anything hooked to the hear riser since 1975 or before. The first intake gasket I changed had a solid gasket on one side of the crossover, which I've continued to block off with any intake gasket change.

The heat riser defaults to closed but opens on startup and after about 2-3 minutes of running clangs at idle along with the lope of the cam, or when accelerating it just rattle-clangs along the way.

I thought about welding it open when I rebuilt it in 2012. Kinda cool that it could still work, but it is useless for my setup. I'm not gonna find any choke butterflies, nor would I ever hook the choke up again.

Even back in the 80s when sub zero in Utah, it was pump 3 times and start it for a couple minutes. Pump it three times, set the fast idle, start it and then let it warm up. No choke was needed nor crossover.

Just curious what others have done. Weld it? Wire it? Just continue to let it clank?
