I just picked up this motor and I want to make sure the timing is correct.I know this has been talked about many times before,and i did search it,but it was a lot of questions unanswered.I assume the #1 cyl. is the top cyl. on the starboard side.On the flywheel, there is 2 sets of timing marks,,1 says #1 cyl,and the other says #2 cyl rope...I have a long plastic arm coming out from under the flywheel on the starboard side,,and a smaller bolt with a rubber stop under the port side of flywheel.Do I need the 7/16 plug gap tool on the #1 cylinder plug only.I know the timing says 18 degrees,so I assume that I need to set it at 14,,unless running down the lake,,,which is possible.Any other pointers would be much appreciated.
