I have a 1995 130HP Johnson where I am trying to do a timing check using Joe Reeves method. The service manual states a 18 BTDC timing and if I am correct using Joe's timing method I should be reading 14 BTDC at cranking speeds with full throttle right? I ask because I am reading 24 BTDC. I want to make sure I am doing this right because if its reading 24 and I have to set it to 14 thats a huge difference.
Also I didn't use a spark tester I just installed a sparkplug and grounded it to the heads with a tie wrap but I cant see that being the difference.
