Take your time rebuilding your carbs. I've tried to cut corners and it never works. Sadly, There were several great threads on FZ1OA.
Even experts like Ivan will tell owners not to de-rack the carbs into individual units.......... but I wouldn't do carbs without separating them and replacing the fuel log O-rings (Item 58) in the fishe. It's a bitch to put the carb balancing springs back in after de-racking (hint use heavy thread to tie them closed on two sides, then cut thread with exacto knife once in place. Hemostats (roach clips) help to place the springs where they need to go. I've had the fuel log o-rings fail and start leaking, that why I always replace them. There were also some great threads on FZ1OA about the McMaster Carr O-rings alternatives to OEM. Personally I replace every o-ring.
There might be some good threads on carbs here, just haven't looked.
The other electrical failure that seems like a carb problem is bad intermittent spark plug caps and the connection with the H/T leads. They are easy to take apart and clean up. Spent weeks on carbs to find out that was the culprit.
