If all else fails you could try earthing the source coil to the coil mount--bit fiddly soldering a terminal & taking the insulating off the copper wire. I'm thinking it earths in through the lighting or charging coil at the moment.

It's messed up. It had fallen out on its own.

Sorry, can't fall out on its own. If it was in one piece then probably got pushed out as the flywheel went on. What usually happens with a broken key is once flywheel is off, you need to tap the broken bit out of the crank plus same with the bit left in the flywheel. Never mind. Hope you have some good luck soon. Have you got a good holding tool to be able to tighten the nut good & proper.

I wish we could transport RT325 around the world somehow.  I bet you could arm him with a rock to use as a hammer, and an old butter knife for a flat head screwdriver (and the pointy end of a rat tail file for those cross head screws) and he'd have most of the bikes here fixed in about 5 minutes. 

 

Lots of great ideas.
I think tomorrow after school I will mark the stator and pull it off, carefully routing wires away from the shaft. 

 

Yes Mark i used a "dam big rock as a hammer to straighten my mower blade after i let the mower down on top of it in long grass & broke the crank key haha. I knew the key had gone as pulled the cord out of my hand restarting, but got it going to finish the farm drive. Key No4, slow learner haha. OHV Chinese motor has been amazing. But neighbor 20 years ago hit the concrete drive edge & fair bent the crank on a Briggs motor. Blade wouldn't revolve so bent. So nothing to loose & had a long galv water pipe so bent it back & it carried on like nothing happened. I guess it was bent in the bigend crank web area & expected the crank to break but it didn't. Doubt i'd get that lucky twice--or not on that mower lol.

A local hack wired it. (Me)
have sent pics to deet for a time machine estimate.  Probably should have routed wires to the back.

See on bench
