Geez, I knew that MSD components had been outsourced to China, but damn, now the owners too???
Grego, I'm not sure which MSD box you have, but they are all very similar. Look on page 9 of this MSD instruction manual and try the spark test when you get back. It will help you isolate the problem. Keep in mind that a bad coil will often seem good until it heats up, although in your case it seems you have no spark when the engine is cold. Believe it or not, this will simplify your troubleshooting. Good luck!
