      Any one know where I can get a carb kit with a float?

        You will have to make a float. Check home improvement and hardware stores. You want a cork in the natural form as apposed to compressed granules. Gasoline could dissolve the binder. Another option is the Mercury closed foam float (Mercury  number 1385-8983 – NAPA number 18-7208.). You will need to cut it down to fit as well.

        Cork

        A "Boathouse Repair" is one that done without having tools or the skills to do it properly.

          Terry,

          Do you have a parts list for that unit?   I do have some individual parts, to include a float, providing numbers match up.

            Thanks to both of you!  I am restoring this unit for a young friend of my wife.  Looks like I will go with the NAPA part.  There was lots of “Crud” in the bowl.  Ed, is yours a NOS part?

              You will also need new leather Primer Seals and instructions to install them. I am the guy that makes them. Send $10.00 sash and a self addressed Stamped Envelope to me; Lloyd Lautner 9289 North Long Lake Road, Traverse City Michigan 49685.

                Parts are NOS, however not selling unless we have a part number match.  Give me your part numbers and I will sort and advise.

                  Thanks Ed!

                  I will get you off a check ASAP.

                  This engine seems to run High RPM’s and Low RPMs without touching the speed lever. I am assuming it is leaking air past the seals.  The float seems to float when I tested it….

                      Terry,

                      See my previous response.  I am not aware of a carb kit for that model.  Send me a list of part numbers you need and I will advise
