Rough Engine - maybe some good tips

After you check the cap and make sure there is no moisture or carbon tracks, start it up again. If it runs OK, you're done. If it still runs rough, try the down home redneck approach; pull one spark plug wire at a time. If it runs a lot rougher with a wire removed, that cylinder is probably OK. If it runs a little rougher (or even no change) that wire is suspect.
A Harbor Freight digital multimeter meter is a very good way to check those wires - they cost less that $10 and may even be free if you have the right coupon.

Set it up to measure resistance (we'll talk you though that if you need it) and measure the resistance of the wires. The wire that looks a lot different from the others is suspect. If you have the Spiral Core wires, they all should read less than 100 ohms. Radio suppressed wires are a bit different, but if you get one that reads much above 50,000 ohms I'd suspect it has an issue.
Let us know what you find. We need a success story just now.
P. S. Do one wire at a time, we recently has a "runs rough" issue where one of the group swapped wires.
