I just re-built the carbs and need to set up engine to factory specs.<br /><br />What is the idle speed timing spec. for a 1973 Johnson 50 hp outboard. My manual gives only the WOT timing at 19 deg. No spec for idle timing. The factory settings were tampered with by "others" and later by me because it is called the "idle speed adjustment screw" in the original owners manual. However, it changes the idle speed timing.!#*?! What's up with that?<br /><br />After the low speed timing is set correctly, how should the idle speed be set? My manual is unclear.
