Carter 750 float level

Nothing is set/adjusted at this time, didn't run it long enough. Timing/tach light died on me as well. Normally it idles about 900, automatic, don't know much about the motor, it's the only part of the car I haven't had to go through, but probably soon. Saw fuel being pulled through the primary boosters, figured I'd lower the fuel level and swap the needles to solids & see what happens. When I can get back to it, of course.
