i am having problems with this motor having no spark it ran fine when i took it off my jon boat now i put it on my pontoon and i cant get spark. i have checked the statorand everything else with a ohms meter and everything seems to be fine. I am confused can someone pls help me out.
 
Does this engine have a wiring harness leading to an ignition switch, or simply to a push button to stop the engine from running? If a wiring harness, does it also have a kill switch & lanyard?

Remove spark plugs. disconnect the black/yellow wire from the powerpack. Do you now have spark?
 
I assume that you're saying that it has spark with the black/yellow wire disconnected?

If so, how about this question that I asked (below).

"Does this engine have a wiring harness leading to an ignition switch, or simply to a push button to stop the engine from running? If a wiring harness, does it also have a kill switch & lanyard?"

You need to spell it out for me to eliminate a lack of communication.
