Carburetor float levels, Zenith B and Tillotson

Posted by Larry Jenkins on April 06, 1998 at 14:14:46

The B engine in my 30 Coupe runs very rich and little power even with the dash control off, and will even backfire occasionally.The timing appears to be correct, as it starts right now and idles well. I have been told that perhaps an incorrect float level may be the problem.
I an going to buy Bratton's Carburetor Fuel Level Gauge, his Part No. A9599 shown on page 57 of his April, 1998 catalogue. He states in the description that the fuel level should be 5/8" below the seam of the carb.I have heard 1/2" also.
Is 5/8" correct for a Zenith B carb, and what should the level be for a Tillotson?Any other thoughts on what may be causing a very rich running engine?
Many thanks..
