Hi there friends, new to the forum. Tried a quick search, couldn't find an existing topic.
I bought a Super Sport a week ago for very little money, and it starts first time (kick) but runs fairly rough. It only really runs on choke, even when warmed up. I'm pretty sure the guy left gas in it over the winter, so I took the carbs off to check them out and my suspicions were confirmed that the float bowls were fairly grimy and one of the floats was stuck. I have a brand new carb rebuild kit from CB750supply, new jets, etc.
What I really want to do is completely disassemble the carbs and run them through my friend's ultrasonic cleaner and then blast out all the passageways etc, and then install new gaskets, jets, floats, etc. This is pretty easy - I took Carb #1 off the stack and disassembled it, they're pretty simple. However, I am perplexed and intimidated by the idea of unracking the whole assembly because the spring-loaded assembly for the choke and throttle looks extremely complex and I'm concerned that if I do actually manage to take it apart I won't be able to put it back together properly.
The bike is ready to go otherwise - the timing is spot-on, everything works, oil pressure is good, tappets/ cam chain/ etc are all spot on.
I guess my question is as follows:
Does anyone have a link to a video or step-by-step guide for disassembling these particular carburetors?
Every guide I've found so far has been for a very slightly different bike with slightly different carbs, and the one video I did find for these carbs skipped over the spring-loaded stuff much to my disgust.
I'm very tempted to do a quick and easy clean on the lower halves of the carbs and call it a day for the season. Clean the bowls, blast out the passages and crevices, reinstall jets etc and get riding. The top halves of the carbs look pretty damn clean to be honest.
