I need to set the timing on my 93 v4 90degree 115hp. In my seloc manual, it says to adjust the timing at wot to 28degrees and idle to 3 degrees. It appears that both adjustments are done at the same thumb wheel. my qyestion is can i set idle timing to spec and be fine on my wot timing? The reason im wondering is because i dont have a test wheel or body of water near by to test the wot timing.
