Vernon,
Quite often an engine that has been in storage for a long time gets moisture into the coil and high tension spark plug lead insulation. This moisture will short out the affected parts and be a cause of no spark. A quick and dirty way to see if this is the problem is to spray the coil and high tension spark plug lead with WD-40. The wait about a half an hour before you try to crank the engine. Do not get the WD-40 on the points. The WD-40 drives the moisture out of the wire's insulation and removes the current's path to ground. This will only work if moisture is the problem. I would suggest that you replace the spark plug lead even if this WD-40 trick works. If the wire is the culprit, this will only be a temporary fix. It will short out again after the WD-40 dries out completely.
Don't use anything but WD-40. WD-40 was designed to drive moisture out of electronic equipment
(amoung other things), and it does this quite well. I have used it on the inside of distributor caps also, but again, if it helps, I would change the cap as soon as possible.
Let me know if this helps. It may save you a trip to the small engine shop.

Good Luck,

Britt
