Motor has been sitting for a while. Ran great when put up. Will turn over. Has no spark at spark plugs. Have any ideas where to start troubleshooting. Ignition switch took a little working to make connection at first. Also has a kill switch on the shift/ignition box.
 
You didn't mention the model, but your first move is to find and disconnect the black/ yellow tracer kill wire at tne switch box and check for spark again. If yes, find the tilt switch (if equipped) and disconnect it. With the wire reconnected, again test for spark. If no, look for a remote controls problem.

First,, Thank you for your time and help!!! Not sure of model#, Motor is 70hp. However I disconnected the black/yellow kill switch wire @ the switch. No Spark, Disconnected the tilt switch, No Spark. Reconnected the kill switch with tilt disconnected, no spark. When you say remote control, what exactly do you mean and how do I troubleshoot it. Is there anything in the ignition switch itself that would prevent firing?? What would be the next step?
