When I lossen the lock nut to adjust the floats I have fuel pumping out out of the adjusting mechanism. I don't remember this happening with prevous holleys. Any idea what the problem is? Had a friend put a kit in it but I think he did something wrong. Also having trouble getting the float levels low enouth so no fuel comes out of the sight hole. lts a swap meet vaccum secondary 750 that I'm about ready to give up on and buy a new one.
