Does anyone have 1 of these? I'm trying to make sure I have the right fuel level in my float bowl. The manual states to have the "0" on the gauge even with the carb./float bowl mating surface. They say to have the fuel level ".5" +/-1mm. I have no idea how far down from the mating surface this is. I had gas really coming out of my drain tube off the bottom of the carb., now I have adjusted the float lever and still have a drip. It's better but not fixed. I concerned that I may be lowering my fuel lever to low and hiding another problem. I figure as long as I know the fuel level is correct and if the prob. still persists I def. have another problem. For all I know I may just need to lower the floats a little more. Can anyone help me.
