Q-ball, the biggest problem, as downunder knows, is the changing head and siphon effect of having to high a tank position..

It just pisses out of carbie if it's open just a crack.

Need to investigate this uniflow tank stuff downuder, could be a winner or it could cover my model in raw fuel!

When in doubt, i'll just fit a pacifier to it!

BTW O.S. 61 sf, grrrrrrowl!
