Thanks for your thoughts guys.

tc , I adjusted the idle mixture and the timing a tiny bit on my 216 and have 20" vac the engine starts perfect and the hot tubes get REALLY hot , maybe I could try lagging the tubes. I have no idea what the Zenith is off. I just threw it on the engine (4 yrs ago) 'cause the original W-1 was weeping bad .

Jerry , I do so hope you are wrong about this issue.
