you can use a spark tester that is basicly a plug with a clip on the side to ground it. An old plug would do the trick just fine. Should have a fan blowing on the engine to help cool it. Don't turn the screw in until it almost dies, just until it starts to run a little rough then back it out until it starts to run rough set half way between the 2 points. So easy even a caveman can do it. You don't have to disconnect a plug wire if you don't want to but if you don't it makes it harder to tell when the side you are working starts to run rough.
