Attwod water heater issue

So my water heater is not working right... Basically it's starting alright (DSI), but with a huge yellow flame at the end of the burner tube instead of a nice blue one. It keeps trying to re-light even when running, as I assume the flame is not hot enough to warm the thermocouple?

Every once in a while it will also flare out of the venturi portion of the burner tube too, big old yellow flame that I can blow out easily. It seems to me that it's not getting enough gas flow.

Stove works fine, and the water heater is mounted in the cabinet right behind the stove so I'm pretty confident I'm getting gas to the water heater.

I removed the end of the burner assy from the valve, and unscrewed the jet. It looked good, I ran some carb cleaner through it, but no change. The tube looked good too, no blockages (at least from the jet on out).

What next? :)
