Hi Rock.

You know, you are absolutely right. I guess it just became a habit I learned from someone and just do it automatically. I watch the air-bubble move through the fuel line until it reaches the carb and the fuel flows freely without air bubbles in it. I use S&W 15% nitro 20% lube mix, the fuel is red, well, actually a sort of pink, but it is very visible as it moves to the carb from a full tank. This usually is what is expected on the first flight of the day from fueling up an empty tank. I guess it comes from 'priming' a cold engine, I guess..

Thanks for the input. I ought to just follow suit and do it right..

DS.
