I picked my wife up an old 82’ Yamaha Maxim. It will only idle with\nthe choke on, as soon as you kill the choke it dies and as soon as you\ngive it any gas it dies. I’m guessing it’s the carbs. I took the air\nfilter off and shot some carb cleaner spray up into the 2 intakes with\nit running and managed to get it to rev up a bit but then it started\nshooting this nasty looking brown crap that smells like gas out of the\nhole below and centered between the two intakes when it revs. Is there\nany way to fix this thing without totally taking the carbs off? Any\nsuggestions if I do have to take them off? I cleaned out the tank and\nchecked the petcock and they’re both clean. It did sit for at least a\nyear before I bought it. Also if anyone has a service manual for this\nthing on the computer that I could get off of them I haven’t had time\nto order one yet.
