Now that I'm heating the fuel, it ran so rich I had to turn the fumes down. I was riding around and killed the motor from it being too rich.
I've made a couple of minor tweaks since this video to tighten up some vacuum leaks. Also made the line going into the fuel tank a traditional bubbler intake tube. This was the last tweak that caused me to run too rich.
That's not a problem of course because I can always turn the fuel down, not making enough is the problem you don't want to have.
