Topic: #2 cylinder hot, 1973 CB500

[docoffey]

Finally have no 4 carbs dumping gas out the overflow tube.  Started it up, Real high RPM, 7000, #2 exhaust pipe turned cherry red, finally got the rpms down to 1100, running rough, backfiring, uneven idle, finally just shut down.  I'm thinking #2 is too rich, if so, how do I fix it? I've cleaned and put in 3 carb. kits,  The plugs are new.  What else should I check?
thanks.

First check to make sure you have fuel flowing through both sides of carbs

Thanks for replying.  All four carbs are getting fuel. I used a 1/8 drill bit as a spacer to set the spacing on the each carb. I do have the idle down to about 1100 hundred rpm now but it is still backfiring after it's warmed up and not running smoothly  the idle speed is not steady.
I do not know how to sync.  the carbs, nor do I have the vacuum gauge setup for that.  And yes I'm afraid I am running on the stand.  Not sure I have another option.  How do I make is less lean?

thanks

Also the floats were set a 21 mm. on the bench.  #1 was not shutting and dumping fuel so I "tweaked " that float a bit and it stopped dumping.

Not sure how to tell if all four are getting fuel equally but all are getting fuel.

Sounds like some good ideas that I think I can do. Thanks for the help and advice. It's Sunday so I won't mess it today, but hopefully can get started Monday. Wife wants to go fishing so it might be later. Anyway I sure appreciate all the advice you folks provide on this forum.

And yes, the 1/8 bit was the spacing for the slides, they do all move equally.  I'm pretty sure all floats are installed correctly, but I will recheck. 
thanks
