I used it for a while about 10 years ago. I remember vaguely the ignotion advance plate turning on its own when pulling the pull cord causing problems. I fixed that. Now it runs on one cylinder. Points seem good, 20 thou, condensers seem ok. I tested them with a multimeter that counts up to 10 after you ground them. One counts up faster than the other. I'll need to test them with another multimeter that makes more sense. I need to test the HT coils and the driver coil. I'd say its the HT coil. They are bolted on beside the spark plugs The nuts on them are hard to get at. I can take the whole bracket off but thats held on by bolts in the head so I'll need a torque wrench to torque the head afterwards. I remember changing the impeller but didn't understand the care needed putting the shaft back into the engine taking care not to damage the cork seal and gudgeon. I think I got water in one cylinder as a result. Thats ok now. That one surprised me. I know they dont have high compression but pulling the chord alone I feel compression is good. Its a clean engine. It's was weeping oil from the gearbox at the prop. Thats fixed. There was no water in the gear box. Its a good engine. Clean. Heavy enough for a 6. I'd say I could put a bigger carb on it. The ignition plate is one I dont see when I search on the net for that engine. But I've seen a few for sale in France that come up. I'm in Ireland.Does this motor run ?----2 sets of magnets inside the flywheel ?----It is the 6 HP marketed overseas.--The extra coils are there to run boat lights.---Have never seen a 1975 with that ignition here.-----These are wonderful smooth running fishing motors.
I think I'll do that and the points as well. I found the problem I believe. There's a little play in the stator plate which affects the points gap for the plug thats miss firing. I took off the stator, it was oily around the shaft. I cleaned it and greased it. It worked better for a while because if the thickness of the grease reducing the play. Im not sure how to fix this without replacing the stator plate but as the ones I see for sale are used I cant be sure if there would be excess play in the one I was buying. Heres a few pic of the assembly. Can anyone inform me if anything is missing please?btw... a good VOM test on a capacitor is not conclusive even when it test good. You realy need a high voltage test apparatus to test a hogh voltage leven to check leakage. may was well pop in some new ones.
The year appears to be 1975, and indeed with 2 sets of points it would probably not be 'wasted spark', I made that assumption because of the single coil.
