I have a 1978 Mecr 200 20hp motor with the thunderbolt igntion. I went to go fishing this morning and the thing wouldn't start on me. Ever since I took it out this year it has been starting hard compared to before (it used to be one or two pulls). <br /><br />After messing around with the motor all morning, I found a broken wire at the kill switch, and the ground wire at the "black box" (ignition module?) had a break in the insulation. I replaced the two wires, hoping that they were the problem, but the engine still won't start. <br /><br />The engine has new plugs; the proper NGK gapless units from the dealer. It's getting plenty of fuel, so I know it's not a fuel problem. <br /><br />Any suggestions on what to check next? I would test the coils and the "black box", but I don't know how to as I don't have a service manual. <br /><br />Any help would be greatly appreciated.
