Re: 1949 johnson5.5 hp electric problem
Hi DR<br />Your TN26 uses what I refer to as the early style ignition. So Napa won't be able to help with parts,your average dealer is out also. How ever they may have leads. The good news is coils on these models rarely fail,(not to say they don't or can't). The problem of no spark is usually do to the points sets being dirty and sticking. These point sets are getting hard to find NOS and when you do find them they can be spendy (my opinion). To repair this problem remove the points. Clean the contacts and the little bake-a-lite actuating sticks. these little sticks often get stuck, sometimes real bad. Take your time and be careful not to break them.As Rick sttated the point gap is .020. Now to remove the fly wheel. Remove the recoil starter (if it is still there). Leave the dogs attached to the fly wheel. Just unscrew the fly wheel nut, the fly wheel will pull itself. If those parts are missing, you will have to use a puller as directed. Once the fly wheel is removed you may remove the entire stator plate (ignition) via a single clamp screw located in a tunnel under and to the side, just loosen it. The proper mix ratio is 24:1. The 16:1 confusion stems from early make it easy thinking. These are or were sort of the model T fords of outboards,everybody had one. Do to the fact that these motors did not use 6gal tanks, folks would have to do a math problem each time they wanted to mix fuel. So OMC just made it easy to mix a gal at a time. The closest common measure was 1cup or a half pint. This equaled 16:1. They also recomened the 16:1 ratio when using oil of unknown quality. If Moble outboard oil or other good brand of outboard oil was available you could get by with 30wt. nondetergent.Your motor being a TN model has a neutral clutch feature. This is nice, earlier models were just direct drive. If you have more questions just ask. You will need to remove the gas tank before you can remove the stator. I probably forgot a few other things as well.
