I just pulled the timing module on my XR4 and want to check/set the timing. I am familiar with setting timing on cars, but have never done so on an outboard. From what I gather, they are set by adjustment screws. I plan on setting the WOT timing to 22* static (=24* running WOT in water?) and the idle timing to ~8-9*, figuring I may have to adjust it in the water to get a great idle. When I set the timing, I will pull/ground the plugs, hook up the timing light and remote starter, and disconnect the throttle cable. When cranking the motor over, I will move the throttle arm to WOT and adjust the WOT stop so I get 22*, then back to idle and set the idle stop at 8-9*. There are 4 stops on the arm that I can see, and am unsure which need adjusted. In the picture below, are # 2 or 4 the idle stop, and are #1 or 3 the WOT. What are the 2 stops that are not for timing? Do they have their own settings? Also, I have read about adding a jumper when removing the timing module, but others make no mention of it. Other than removing the white/black, red/black, and black wire for the module, is there anything else I need to do (other than set timing)?
Thanks,
Brian
