I just had the engine rebuilt. All three cylinders. I got it out of the shop and took it out for about and hour and a half in March to break it in. Everything appeared to be ok at that time. I then took it out last week for the second time. The engine cranks fine. It's only running on the 2nd and 3rd cylinder. The top cylinder is not running correctly. When I pull the spark plug wire off there is no spark. I pulled the plug and it was clean, I switched plugs and the plug worked with the other cylinder. I switched the coil pack and that's not the problem. If I take the spark plug wire from the 2nd cylinder and put it close to the 1st cylinder I would get a spark. Any ideas??
