Thank you all for your help and comments, I will certainly check for leaks after the bench test.

Thanks

If for example you just open the throttle mechanism and place a spacer underneath that screw to stop it dropping the slides, then any resulting gap under the slides can be set to parity across all four, doesn't really matter if it's 3, 5 or 10 mm there, as long as you set them the same, then take out the spacer to drop the throttle mechanism back to correct position.

That's a neat idea Nigel - what size spacer would be ideal?
I'm thinking of trying out that idea on my spare set of 400 carbs that need bench such as I have finished overhauling them. Would 3mm be about right? Does this method impact on the throttle quadrant fully opening the carbs?

jst as expected, fuel leaking and need to order a full set rebuild kit x 4 (complete with float needle and seat) any ideas, or does anyone on the forum sell any? (its the 1976 750F1)
thank you

Bryanj:
Dont buy kits the sizing is not correct just strip and clean the brass in an ultrasonic, you could ask Nurse Julie if she does the O rings for those

I fitted keyster seats and float valves on my CB350 four and I’m now getting intermittent fuel leaks. Will be replacing them with the correct (but costly) parts
