Reply To: 1958 10 horse Johnson carb rebuild

Dale,
I;ve had a similar issue with a ’56 12hp Sea King. For me, the problem was that I couldn’t back the needle out of the carb body. It would just turn and turn but not back out. I found out that that bushing was threaded for the needle but just inserted into the carb body. Then the packing washers and nut held it in and still while the needle was screwed in. Maybe look inside the carb, where that needle goes and see if it is threaded for the needle (not just the packing nut) in there.
But, I guess you asked how to get it off. I soak all my bare metal parts in laquer thinner. And am patient. Some one told me once that screw drivers that fit the screws and patience are the most important tools for rebuilding these ol’ motors.
I just started my 6th rebuild. Its a ’54 10hp Seahorse. Similar. I’ll take a look at mine and see if it has that bushing thing.
