BME-50, spark plug is bad??
 

Hi,

I can't get my BME-50 started, so I removed the spark plug, turned on the ignition and flip the propeller. I do feel a little shock when I turn the propeller, if I hold the plug by the threads, but I see no spark. It is obvious that the ignition is doing it's work cause I feel it. Is the spark plug supposed to visibly ignite?

Also, the sprk plug cable has a groung log, is it supposet to be attached to something? Does it make a difference? I don't think that the lug was attached to anything before, and the engine was running good.

Thanks,

David
