Re: Unburned fuel

I would think the best thing to do would be to almost run the tank out before filling it. Always keeps fresh gas and a fresh, properly mixed mixture of fuel/oil. That was my thinking when I ran the return line back to the tank. Told him to not always fill up when the tank was only 1/2 or 3/4, as after many tanks, your mixture may go off. Perhaps.

I have not added a vent line to the carb intake on the ones I have done. Good idea though. By the time it runs back down the line, and is remixed in, I don’t feel there is any additional threat, in comparison to a normal, single line tank venting to atmosphere. But as stated, an additional improvement, and good idea.
