Doesn't sound normal to me. I have touched mine, and never gotten a shock.

Not ever normal to get shocked by anything. I would definitely look into this. Is the plug wire wearing through anywhere?

What type engine does your model have. Its not normal to get shocked when moving the throttle. Most snow blowers have a small tab with wires attached on the throttle that grounds the spark when you push the throttle completely down. I would check that to see if anything is broken or wires are frayed.

Where are the condenser and points setup? Under the flywheel I assume. You might have to pull the flywheel. Unfortunately all of my ignition system experience is with outboards so I'm not sure if you motor is the same.

With an outboard I would pull the flywheel and look at the coils for cracking. Next look at where the spark plug wires pass through the base plate. Also there are wires between points and condenser. There are not to many wires on a points motor. My guess is the motor is not grounded well and you are.

thanks for the replies, checking all visable wires and all looks good so far, i'll have to dig deeper to see, its an 11.5 tecumseh engine, this runs great ,would never have noticed the problem if the throttle lever hadn't broken, noticed it when trying to shut it off without the red plastic knob
thanks again

I have a quick question. Were you holding any other part of the snow blower when you got zapped. Also You said the throttle is broken. Is it just the plastic part or is if farther down. If you want send a picture of the throttle mechanism and if something is obvious a forum member can point it right out. If your snow blower has a key shutoff I would try using that than pushing the throttle past the idle position.

Garage
Your machine has a throttle that can also kill the engine. There is a wire from the engines ignition coil that runs to the throttle lever. Somewhere the wires insulation is likely cut and grounded to something it shouldn't, like the throttle control itself. It should be insulated but somewhere it isn't and it's grounding the ignition through you !! When you move the throttle all the way to slow or stop that lever should make contact and ground that wire to the body of the engine shorting out the coil. Yours has that voltage present in the throttle arm apparently and it's jumping to you.

There should be a wire running between #100 the coil and #200 the throttle bracket assembly. Usually it's a white wire but it's not shown in the diagram. Might be part of the wiring harness itself. Maybe it's just knocked off the spade it connects to at the bracket and grounding to the lever itself ??

Make sure the windows are up before the snow plow goes by !!
