1946-7 5HP Sea-King

[cmb3366]

I've got a Model Number 74GG9011A Sea-King that I would like to restore to running condition, and I've got a few questions. What Oil Ratio should it run 16:1 or 24:1?. Also, I am not getting any spark, I assume the plug wires need replaced due to their poor condition, and the points could probably use some attention. My problem is getting at the wire connection and points. I've got the fuel tank, recoil housing, and the flywheel clutch off, as well as the nut on top of the flywheel. I assume the points are located under the steel 'cover' mounted to the flywheel, as that is where the sparkplug wires seem to lead. But I can seem to figure out how it is mounted, and more importantly, how to tak it off? Also, once I get at the points, are there any good sites for finding replacements should they need it?

Any help I can get is greatly appreciated.

Good morning,the original fuel mix is 16:1.use TCW3 rated oil.I would stick with that unless you get specific info from the guys at aomci.org
(antique Outboard Motor Club)You will need a Hormonic balancer puller to get the flywheel off.Available at Harbor freight.Use quality bolts in the bolt holes in the flywheel.Keep the fly wheel nut on loosely to protect the threads.Tighten the big puller bolt good and tight And whack it (the bolt)a couple of times pretty good,retighten and repeat as necessary.Should pop loose.
These old style coils don't usually fail. The odd looking points no doubt will need cleaning and adjusting .020.The points are used on some other Gale products and on the Johnson TD20 motors.Sometimes seen on Ebay.
possibly at aomci.org.Be sure to use solid core plug wires (wire centers).

It is best to take the points apart (one at a time so you have a reference) and clean each contact individually. Watch where all those little insulators go, and don't lose them! Clean all the parts with some electical spray from the auto parts store. Clean the contacts with some 400 grit wet-or-dry sandpaper. Try to keep them flat, but you won't succeed and they will be slightly convex. That's good, the way they are supposed to be.

The plug wires are soldered to the coils. If you don't know how to solder, learn on something else. They need to be tinned, then soldered as quickly as possible and still not get a "cold-solder" joint. If you do know how to solder, you know what I mean.
