Ron, What did the plug look like in the misbehaving cylinder ? Was it wet, dry, oily ?
Are you using a pulse fuel pump ? Is it located above or below the pulse port on your engine ? If the pump is below the pulse port, you will have to drain the pulse line to the pump after every weekend. Oil and fuel will get into the line and limit the pumps ability to pump fuel. Happened to me ! Are you using fuel filter(s) ? If you have one for each carb, you may have a plugged filter. As you may have noticed, I think your problem is fuel related. I suggest several things. 1. If you are using a pulse pump, completely rebuild the pump. If you are using an electric, make sure that it works OK. 2. If you are not using fuel filters, start. I suggest one in each line between the pump and carb. 3. Completely disassemble and clean your bad cylinder carb. Especially look at the top of the float valve. Dirt on top of the valve will at one moment block fuel and next let it pass. Very frustrating. On second thought, do both carbs. 4. Check to make sure that both carbs are opening wide when your pedal is at the end of its travel. 5. Make sure that the main jet metering rod clip is in place. 6. Make sure that your float level is adjusted correctly. Also make sure you don't have a flooded float.
