      The key looks fine.  A couple of questions:  Did you adjust the point opening to 0.020″ on the high point of the cam?  Also, from the coils, one wire goes to ground, the other to the set of points that is counterclockwise from the coil when looking down on the mag plate.  Maybe a photo of the mag plate might help.

      Thanks for the reply Tom ,   I got everything set and wired properly .  But there’s  a lot be to said for cleaning the points even if they look clean ! 🙁

      Now on to fuel  , This should be fun.  I have to find preliminary carb settings and install a fuel pump conversion kit.

      Any guideline would be appreciated , Thanks

        RK initial settings will be a turn and a quarter on the low speed.  Around three quarters to one turn on the high speed.  A little rich at startup usually helps starting.

          Well, that key definitely looks deformed.  How does the keyway slot look in the flywheel?  I would certainly replace that flywheel key.

            “Also drift key on crank looks like its installed angled , is this normal ?”

            A service bulletin from ’71 says it should be parallel, but it doesn’t mention the 10 horse. Is that an oversight or is there some reason the 10 was excluded? Could it possibly have something to do with the spring arrangement below the cam and above the carbon seal? Because that’s the only thing I see different from the other motors listed. I don’t know, maybe others have insight into this.

              That key looks like dog doodoo, is it chewed up?

                This is a good question for sure.  I have often wondered about the differing recommendations.

                  SteveD;  interesting Service Bulletin.  Do you have a collection of them?  I search for them when I have time….never seem to come across very many.  Do you have others?

                    You can install the flywheel key as shown in the diagrams and that’s good. When installing the flywheel, however, there is nothing to prevent some rotation in the key. Many of the keys that I’ve seen have some noticeable rotation.
