I have an old rotor tiller with a 5 hp briggs on it. I'm not sure of the year, its at least as old as the 1970's. The problem is, it has no spark. I took the engine cover off to check the coil for bad connections but nothing seems to be out of the ordinary. I noticed some wires that go under the fly wheel and from some of the other posts i've read on here, there's a points ignition under there. How the heck do you get the fly wheel off?? That may not even be the problem but i'd still like to know how. Is there a way to test the coil? Any thoughts?? Thanks.
