Off of a forum...

"about float level. It has been my experience that the recommended float 
level setting in the owner's manual for the Zenith equipped Super A's is 
off a little. It causes leaking and rich running/flooding of the engine. 
The Super A Zeniths work best for me when I adjust the float level so 
that the gas in the bowl is just a little lower than the recommended 
setting. That means setting the float level measurement a little MORE 
than the recommendation - I'd say about 1/16" to 1/8" more."

Would this be correct, then?
