On the way to work today, my C model was acting up. It hasn't been started in about a week. After I started to work, it got really bogged down like it was running out of gas, then died. It would restart after a while of cranking, and would run pretty good, then 2 minutes later the same thing would happen. I got it home, and before I shut it off, it was barely idling and ran like it was only firing on 2 cylinders. I do have gas in the tank, and fuel in the (clear) fuel filter. My guess is ignition. Anyone have any other ideas?
