    boyesen reeds and rebuild

    73 115 johnson<br /><br />I have a set of boyesen reeds to install in this motor. Question is should I install them prior to first start up or should I do the initial tune with the factory reeds. I'm thinking a backfire could damage the boyseens. Dropping the idle jet size from 30 to 25 per...

    To bore or not to bore

    73 115 V4.<br /><br />When going through a motor what are your opinions on boring cylinders still in spec. Trying to make his this thing real fresh.
