Alright guys, I'm new here and excited to get put to work with all your solutions. I recently bought a bike, my first, a 79' CB750L. It needed a carb rebuild, which was a pain. I rebuilt the carb, replaced the air cutoff diaphragms and float bowl gaskets as well as the jets. I'm not sure the new jets were the same as the old, because I'm an idiot. I reinstalled the carb and turned her over. Now the bike only runs on (seemingly) the 3-4 cylinder, if that. I was getting weak exhaust from the left side. The bike won't even start now. So I pulled the plugs and they're black as night. I'm not sure if they're firing. Could the reason for fouling be as simple as the rejetting, I wouldn't think it would matter much considering it starts on the idle circuit. Please let me know how I can slim this down to one culprit. Much thanks!
