I never put a lot of thought into this until last year.
A friend of mine got mad when i set his auger down on the handle with his gas tank facing up, and not down toward the ice. Granted the auger was new, its a 2 stroke, and the sales rep told him to always have the gas tank facing downwards when transporting. I have never paid any attention to which way I have sat down my model 30 and I have never had a problem with it.
So is there any actual truth to as why you should have your gas tank orientated a certain way when transporting your auger?
