Re: Increased MPG for carbs?

Think about it, your driving a giant barn on wheels, well about the same shape. You also do not have computer sensors and gadgets to regulate anything, most carbs act like a water hose with gasoline for the engine. Unless you go with a late model computer controlled engine I doubt you will make it to the high teens. The most I have read on here about mpg's was 17-18, but I think they had an overdrive trans.

Good luck though, I'm trying to squeeze every bit I can outta mine.
