I just finished checking the plugs and they were covered in carbon I attached a photo. I replaced them with correctly gapped new plugs and checked for a spark with both wires. Both wires showed a spark. I checked the petcock and when I sucked on the end of the vacation tube gas flows fine. I did notice that when I put my finger over the vacuum tube coming out of the carb and cranked the engine that the suction felt sporadic. I was only able to get the bike started for a short while after I covered the petcock vacuum tube coming from the carb with my finger and cranked the engine. This makes me think that the bike is possible running rich? What do yall think. I tried making adjustments to the carb fuel/air mixture screws by slightly unscrewing to make it run leaner. This had no effect on the bikes ability to start. What do yall think?
