"I have a 1997 v6 Mercury 150. I checked the timing today. My procedure was; I used a dial indicator to make sure my timing pointer was adjusted right. I disconnected all spark plugs and instead of using a spark gap tool, I used old spark plugs and made my own wiring harness and grounded them out. I disconnected the idle stablizer cranked the motor over and the reading I got with an inductive timing light was 9 instead of 21 as the manual indicates. What did I do wrong or can the motor run that far off time? And could you please explain to me in the carburetor section of my service manual it says idle speed/pickup timing is between 2 degree and 9 degrees ATDC. What does this mean? Thank you"
