I bought this motor used, it ran like a champ for 2 years then I took it out last season and it wouldn't even fire. I have ascertained that there is no spark but I don't know if it is the coil, or the E.I. unit or what. My other problem with it is that all the paint is gone from the I.D. tag on the port side of the mount and I have no idea what the model, serial, or year number is (late '80s I guess). The head has a 952 molded into it by the "made in Japan". How else can I identify it since I know nothing about these Suzukis. I will try to attach some pictures.
