Hi,
Yes a little riveted plate on the motor says model D 4019 serial 890720 and on the body it says SER NO RC 610945 model 5.
excuse my stupidness what is the magneto is it the magnetized side of the flywheel or the green thing that the other end of the spark plug cable is plugged into. it has 2 wires coming out of it one is attached to the screw and goes into the green thing the other comes out of the green thing under the flywheel and out of site cant see the other end.if the green thing is the magneto then i unscrewed the 2 screws to look at the contacts to see if they were dirty then put it back together.
I don't know where the kill wire is.
sorry as i said i am new to this but determined to learn more about small motors.
I haven't removed the flywheel.
Thanks
