Yep I also think the "technician" is not too hot.
We are a bit starved here for good help so I will let it ride for a bit and if they don't fix it I will keep chucking bits at it until it goes. I don't want to loose the mower as I like using it when it runs.

The Mower I have has no points it uses a magnet coil and CDI unit - one of which is not working.
Been raining here and I have not had a chance to get it back yet.
Cheers
Duke
