CB200 Carb Sync & Float Level Tips?

OK, how 'bout listing up your favorite methods for syncing the carbs on a CB200 (independent slides) and for setting / checking the float levels.

I've had to completely disassemble, clean and soak the carbs on my '74 CB200 - standard rebuild technique. My synchronizing style is to bench-sync them first, just by eyeballing the gaps beneath the throttle slide and trying to make 'em the same. But, I have no idea where this will leave the idle speed setting.

Next, though, is connecting the two separate cables to the slides and trying to set free play. Here, I just try to sync them so that I can just hear the slight "click" the slides make as they close and try and get 'em together. But, my ears aren't as good as they once were... :)

But this is kinda crude. Anyone got any better suggestions? Anyone drilled & tapped the manifolds for using a mercury-type carb synchronizer?

How 'bout setting float level on these? Anyone fabbed a screw to thread into the bowl drain and connect a clear tube to check actual level? I guess I should start with the manual, to see what it actually says about setting float level... :oops:

Thanks for any tips and techniques.

Every bike I've ever stored for the winter did that when you're emptying the bowls out using that method. As it leans out it revs up. It's not necessary to do it daily, unless you only ride it once a month. For winter storage it's a must.

+1 on that.
My cb450 behaves in the same way. Good to know.
