Before syncing my carbs I would like to set the float levels correctly. I have read that the fuel level should be visible just below the top of the jet nozzle with the suction chamber and piston removed, mine are not even close. What is the easiest and most accurate way to set the float levels without the use of special tools? I have the float chamber covers off now and need a little help here Thanks. P.S. I'm using standard needles and have the black foam floats.
