Thanks Joe and Grumpy.
To answer both of your queries to turn it off you just turn the blue knob clockwise about an inch or 2 and it turns off to turn on turn blue knob anti clockwise same amount.
to start from cold you push the blue knob down onto second button whilst in the on position(wont work in off)to prime and then pull cord.
OK this is what i have done, i went outside and dug out my second iron horse from under the house both i got from my uncle and both exactly the same. This one is way worse than the one i'm working on, the Magneto has crumbled to bits. and is useless, I took off the flywheel and came to a brass colored cover with 3 screws and a tiny spring for the revs(it has 2 positions for revs ordinary or heavy depending on the state of your lawn)under the cover and my god in almost pristine condition are the points and condenser that would be the cleanest part of the whole mower, this is what i discovered, the wire from the magneto that disappers actually reappears under that cover and is attached to the condenser then another wire attached to the same bolt on the condenser goes to what i thought was the kill switch.
Grumpy there is no way that i can see to adjust the gap on the magneto it only has 1 hole on each side to mount so i dont know how to fix the scoring problem.
what should i do now ?
you reckon i should pull the flywheel off my good mower and see what i find ??
