I hooked up my Teleflex tach to my inline 6 (1963 Merc 1000), and I need to confirm the pole setting. Right now it is set at 6P (from Teleflex instruction sheet; setting for "All other Mercury 2 stroke models"). Is this correct?<br /><br />My idle speed is reading roughly 1200 rpm on the muffs, and with the engine warmed up. This seems a bit too high. How do I lower the idle speed? She seems to idle smoothly, and started with 5 seconds of cranking when cold.<br /><br />Thanks.
