i took them apart and put them in a bath to clean them out. worked great. before i did so one cylender only fired when i was above 1k rpm and intermittent at that. at above 70 it was full time, inbetween those it varied with speed. afterwards i could only get the one cylender to fire when i jerked the throttle around and then it only fired a few times in a row then quit. i didnt take anything off of a pair of nipples ont he carborators, they face each other and are near the fuel tube. they are the kind that have a hose on them. can anyone, if they know im talking about, tell me what they are suppose to be for? oh also on the right carb(sitting on the bike) there is one that is by the motor end of the carb. its plugged. what is that one for? im wondering all this because now i cant even get the motor to fire.
