I recently bought a CJ2 and it ran good for the first week that I had it then one morning on the way to work it just died on me. I had half a tank of gas so I knew it wasn't that, towed it home and have bee tinkering with it to try and figure it out. I changed the coil and reset the points to the .020 gap and replaced the spark plugs. It starts now but is running really rough and it backfired a few times, so I think the time is probably off. Does anyone know why this would have happened so suddenly? Any help would be appreciated thanks.
