took the ground wire with aligator clips and clipped it to the head and got

1 spark from the spark plug. just 1.

Also If I hold the kill wire from the coil & hold the top of the plug I also

get a major zap that way as well(one hand)

Just tape off the kill wire for now and dont touch it to anything, Make sure what ever metal surface the plug is grounding to is clean.

kill wire disconnected & the head bolt clean, when I hold it to the head bolt

and hand on the top and bottom I'll get the shock...

When I hold it the same way and put it on the head (threads for the plug)

I don't get shocked.

If your holding the wire and the plug is grounded to the head and your getting shocked the insulation for the wire is probley rotted and leaking through to your hand I would check to make sure you have a good connection between the plug wire and plug then give the entire plug wire a couple wraps with electrical tape or remove the boot and slip some tubing over the wire.

What do you mean by hand on top and bottom? Just tape or clamp the plug to something metal on the engine. Its not worth gwtting shock like that.

The electricity is going through you to get to ground instead of jumping the plugs gap and going to ground. You are creating an easier path for the electricity to travel.

so the zapping means the coil, points, condensor is working? maybe

loosing its punch through the wire? it is 38 years old. rubber dosent last

for ever

Yep, your getting it before the plug.

The last post on page 3 of this thread covers that, another option could be some heat shrink tubeing, or maybe your small engine buddy could splice a new wire and boot on it for you.

Are you still getting zapped? Take a meter reading from plugwire to ground then connect the plug to the wire and take a reading from the plugs electrode to ground, they should be the same.

of course ill get zapped

ground to plug wire 5.72 little lower than before

ground to bottom of spark plug 11.00 than retest it that way I get .ol

it changes back and forth from .ol to 11. when I move the plug wire back

& forth.. But When I take the plug out I get the 5.72 and dosent matter if I

I move the wire back and forth

That tells me you are loseing connection at the plug. The 11 is the resistance of the plug and coil tegether the ol is an open circuit.

To avoid any confusion, the coil has around 5.7K ohms and the plug being the resistor type has 4.5-5K ohms. Thats what you get around 11K when testing through the plug and coil to ground.
