I'm here Steve, its the weekend and I had to step out, let me take a look, give me a little bit here.

Hey Steve thanks for that info, one question and not sure if you verified this but when the unit gets hot an dies, had you by chance verified that the spark has really gone away, now if not then about how long before it will restart ? or how long does it take before it will restart ?

Thanks

I tested the spark with a test lamp tool made for the purpose. Tested the tester on a different 650 , the tester lit up so I'm sure it works. There was no spark(light) on this one for 20 min. or less.

OK so it gets hot and looses spark is what you are saying ?

Do you have access to a multi-meter ?
