Re: 65 90hp johnson
One drawback to this engine is the carb. It is really like no other carb in the outboard line of engine's. It is really four carb's in one single casting. I would think that part's for this carb would be a real problem. The gasket's are quite complex, and would not be easy to make. The last time I rebuilt one of these carb's the needle, and seat's were about $30 apiece, and still available. Again, these needle, and seat's are like no other, and there are four needed. Throw in a electra-matic gearcase, and a rather complex charging system, and go from there.
