Could someone explain to me how the coils work? I tried new coils off a different compatible motor that I know work, with new plugs.
I have a continuity tester, and after cleaning and resetting the gap in the points, I checked with the tester all manner of things including continuity.
I get "C" to ground on both sets of points all the time, whether the points are open or not. I disconnected the "kill" button with no change.
When I disconnect the connector to the primary wire of the coil of each cylinder, I lose continuity to that cylinder (and set of points).
That's true on both sides, which leads me to believe that is what it is supposed to do. Somehow, it doesn't seem right.
I did find that the points were open wider than they should have been (about .030 instead of the .020) but not sure if that would cause me to lose spark, and the engine not to start.
I have the flywheel off now, but somehow I don't feel confident that I found the problem, and thought I'd ask before I put it all back together and find out it still won't start.
PS. It's a new motor to me. I bought it from a guy for cheap, but I don't know the history of it. It's got good compression (95# both cylinders) and I thoroughly cleaned the carb (although it was the cleanest carb I ever saw taking it apart, so I suspect someone had previously cleaned it) Otherwise it appears generally to be in good shape.
Anyone have ideas on further tests to run on the electrical before I put it back together?
