This one is for Pappy, but any help is appreciated.
I have a 1993 Johnson 15hp Tiller, and the O-Ring (#3 in the diagram) that keeps the cam follower in place keeps either coming off or deteriorating, which causes the cam follower to come off and of course the engine will only go idle speed. The issue is, this happens every 4 months or so. I had this engine for 3 years with no issues, and after the first time this happened, I keep losing o-rings. And yes, this boat/engine is stored outside. Most recently, my friend borrowed my boat, and it happened to him, but this time the cam follower and linkage fell somewhere down the motor and he was unable to locate it.
So, my 2 questions are:
1) Am I installing this O-Ring wrong, and;
2) Will the "lost" cam follower cause any damage, wherever it might have gone?
Also, I am currently back in Afghanistan, so I cannot take pics of the actual engine, but carb diagrams are enclosed. What say you, oh great and knowledgable Pappy? (Does flattery work on this forum?)
