How to adjust/set idle timing screws for "Running" & "Cranking Speed" ignition timing
Motor: 1999 Merc 115 HP 2+2
Need help folks. I think I understand the basic premise of how to check timing while running and the adjustments. Is it safe to do the Running adjustment while using muffs?
I do not understand the Cranking speed procedures. The use of the air gap spark tester... is this for #1 cylinder ignition wire off only? If so, what do I do with the other ignition wires? I have read the manual ten times and don't understand the procedures. Also, what air gap spark tester do I use? Does anyone have an example of one?
Any video links or practical advice would be appreciated.
