hi guys, i hope you can help me. I'm currently working on an 81 CB 750 custom all stock. 4 in to 4 exhaust stock air box. it sat for approx a year and half not running. I pulled the carbs broke them all down, had them ultrasonic cleaned and reassembled them with all new parts from complete kit set. now I cant get it to idle. Ive checked for vacuum leaks and don't seem to find any. it is backfiring through the exhaust also. I will add that I had to replace the starter clutch, is it possible I might have gotten something back together incorrectly while doing the starter clutch? I cant even get it to run well enough to sync the carbs.
PLEASE HELP!
