I have been practicing my soldering skills this morning on a couple of spark testers I like but the wires are constantly breaking off of and I am happy to report that my skill level has advanced to the drunk dirt dauber with Parkinson Disease stage. I did manage to stick the testers back together again though. And this time with a much better quality and slightly larger gauge wire so hopefully they won’t twist off as regularly.December 17, 2016 at 6:09 pm #49317
All this progress with only 3.5 hours of YouTube videos under my belt. I am sure I will be ready to tackle the coil wire very soon.December 17, 2016 at 6:36 pm #49320
Ok. Serious question this time. The coil I purchased has 3 wires and the coil on my motor has 4. The new coil doesn’t have the ground wire that attaches directly below the coil. Will this work ok? I have halted the great soldering experiment until this little issue is worked out.
Note: Concerning this little ground wire attached directly below the coil to the mag plate. I noticed it spins freely in either direction. I doubt that is normal. I did check my new coil and all seems good. I just don’t have the experience to know if replacing old coil with the 3 wire coil is ok.December 17, 2016 at 10:36 pm #49328
Without going into detail, SOME motors had "Maverick Spark Suppressors". Those required a separate ground wire for the secondary winding. In other words, they had 4 wires total. Unless I am totally mistaken, your motor does not have the spark suppressors, so it doesn’t need a separate ground wire for the secondary winding. So, securely ground the one ground wire, hook the rest up normally, and you are good to go.December 18, 2016 at 12:27 am #49340quote FrankR:
Thanks Frank. Did my dirt dauber best on the plug wire and reassembled the ignition. I have spark! I only had to make one trip to the hardware store to replace the little bitty ground screw that I dropped somewhere when cleaning the mag plate.December 18, 2016 at 12:35 am #49341
I did mess up the float valve needle though. Gotta find one a new one if possible.February 19, 2017 at 11:03 pm #53293
I gave credit to the wrong guy when I was making the video. Russ at Larson’s helped me out with the right needle and seat. Unfortunately, either I am not smart enough to get the prop to spin or something in the lower unit is broken. I checked the shear pin and it is fine so I really have no idea right now.
Anyway, the Ugly Duckling is back to life. As poor and pitiful as that may be.

Those coils are dang near bulletproof. If it has secondary winding continuity, it’s good. I agree, take the points apart, degrease everything, and polish each contact individually. Be careful not to lose any of the many little insulators. Reassemble & adjust point gap to .020" You probably will have spark.
The clearance between coil and rotating magnet is important. I’ll have to hunt for the specs that I stored somewhere. Most important, it should not be rubbing.

Messed with the duckling a little this afternoon. The gear is spinning freely on the prop shaft. I didn’t see any obvious pin but there’s a good deal of grease. Is the lower unit supposed to be filled with grease or oil?

I watched your video. It seems that the pin #550669 in the parts diagram above has sheared. It may take a thorough cleaning to be able to see the pin? I’m not familiar with this particular gearcase either so I’m not sure if there is anything special to look for. I’d say that pin is either sheared or missing though and if it were missing, the hole would be visible.
