No sign of any electrical current comming out from under flywheel (magneto). Waiting for a puller to remove flywheel, in mean time any clues / ideas?<br />Otherwise a great out boa :eek: rd for it's age.

Howdy, Cleary.<br /><br />Lots of things could cause your problem, from a bad switch to a bad powerpack.<br /><br />Do you have a manual to guide your troubleshooting? If not, get one. It will pay for itself.<br /><br />Let us know what happens. :)

Hi, Cleary.<br /><br />At the bottom of this page, click on Repair Manuals and get access to some aftermarket manuals.<br /><br />For Factory Manuals, there are a few sites that offer those.<br /><br />Good luck. :)

When flywheel was removed, turned out the CDI unit has a small metal tab that sticks out and is in close proximty to the turning flywheel, too close in this case, and has been chewed out - new CDI for me now needed, US $152, any better options avaliable? Will need to be freighted to New Zealand.<br /><br />cheers :(
