:eek: How hard did you Jam it? Its possible to tig it but I wouldnt recommend it. I cant believe the screw driver went through the piston

I dont think its possible to shove a screw driver through a piston. Just get a flashlight and check tho. Also if you shoved a hole through the piston you would have no/little compression. Check the 4 main things. Compression Spark Fire and fuel and go from their. Sometimes a little starting fluid is in order.
In order for us to help you troubleshoot your problem give us some more details, is this the first time you took this bike apart...did it run before you removed the magneto.
Hope this helps man

holy piston! must have had some impact or breaker bar on that thing. Also, you can weld it, by all means, but I would replace it.

also, make sure you find that little piece of piston floating around in the bottom of your crank case before you put it back together, its small, but could could cause some issues.
