I replace the plugs, wires, cap, and rotor on Saturday and on Sunday replaced the ballast and still no change. As for fuel, I've left gas sit a lot longer than that in small engines and had no issue. But there was a quarter of a tank and I added a whole bottle of octane booster thinking that would be enough. Same for the carb, it's only a year old and if it was clogged I should be able to at least fire for a moment on starting fluid but it's not firing up.
