Answer
Hi Bill,

It may be the starter button. It may be the battery. It may be a number of components in the circuit. You must learn how to test these components and properly diagnose the problem. My gosh, you've spent a small fortune on parts. Know the source of the problem before you buy anything.

Do you have a VOM (multimeter)? Do you know how to use the meter?

Do you have the service manual for your MC?

Was the MC stored over a week or two?

Describe the appearance of the spark plugs. Be thorough. The more you tell me, the more I can help you. Include your email address as requested. I return repair files via email. We'll go from here...
