I have a 76 140 horse evinrude that seems to have a mechanical problem with the spark advance when I throttle up. I have a Clymer's outbord shop manual but it doesn't go into much detail about the linkage so some of my terminology may not be exactly right. First, when I throttle up the spark advance is not moving in conjunction with the throttle. I have to manually go back to the engine and move it. There seems to be a lot of sideways slop in my linkage at the pivot point for the throttle arm and the spark advance arm. Also what ever the connecting rod for the spark advance is hooked up to, and here I'm guessing because I haven't taken the flywheel off yet, seems to rotate with a lot of drag on it. I'm guessing this is the armature plate. The engine runs well if I sit at the engine and work the throttle and spark advance manually but from the drivers seat it pukes out. are there any manuals that go into a little more detail about the linkage, and parts list so that if and when I tear it apart I know exactly what I'm looking at and what parts I need to order. I know already that there is what seems to be a small plastic bushing that the throttle and spark advance arm pivot on that is cracked and I know there shouldn't be as much side to side play as what I have in the linkage so this bushing may be worn. And I can't find any info on what or where the connecting rod for the spark advance hooks up under the flywheel. I will be monitoring this post and adding any details as they come up. Any help would be greatly appreciated. thanx in advance
