So I'm bored the garage bolting on a air scoop I bought 3 years ago... and I decide maybe I should check fuel level in the bowls. So I hit the key on for a couple of seconds(elec. pump.) and the primarys come just below the sight windows. First question is that right , should the fuel be in the center of the windows or bottom. So then I look in the secondarys and I'll I see is the brass float. So I turn the key on for a few more seconds. No difference. So i figure its stuck, I grab a pop rivet and its not stuck it's floating. Second question which way do I turn the adj. screw? It's already all the way in...when I shake the boat and trailer(pretty hard ) a little fuel comes out. When I back the screw off a turn it seems to make it lower. Thats all the adj. I have is about 1 turn then I run out of threads. Do I need to bend the float or some thing? maybe take the lock nut and file it a little thinner? WTF??? If it matters it's a 800 cfm dbl pumper.
