* /u/NoobPwnr on /r/BurningMan Thanks again.

You inspired me to spend some more time with it this weekend, and I think I’ve located a possible culprit.

I use this OMC fitting and have it plugged into this aluminum cap. This weekend I disconnected the generator from the 12g outboard tank to remove possible failure points. I ran the generator “normally”, and after about 15 minutes it struggled, sputtered and died.

What you mentioned about vapor locking came to mind, so I inspected the valve and depressed the spring-loaded bit on the lower nipple. This created a quick suction effect.

I realized this piece probably needs to be in the open position for it to vent properly, so I removed the aluminum cap and put back on the OEM plastic cap, and it ran for an hour without dying.

This leads me to believe that maybe the springy bit isn’t being depressed properly by the quick-release valve I use to connect it to the outboard tank.

I think my next experiment will be to either get a new quick-release valve, or maybe find a way to jam the button down while running it off the tank (just for experiment sake - I know it needs to close itself when not in use).

Seem legit?
