I need to find out the year of this motor. 20 hp johnson model number FD-21R. I also would like to know where i could find a air/fuel mixture control nob for it, the screw and all. And about how much it would cost, before I buy this motor.<br /><br /> Thanks

That would be a 1967, 742. The PN for the knob is 312533 (got this number off a '68 parts book)....supposed to be still available from BRP....local John/Rude dealer. 'Round $11.
