Carb number 2 issue..

Hey guys I'm sure this has been answered before but I just cant get my 81 cb 750 carb # 2 to stop leaking out of the over flow. I just bought a new needle and a new float and still it just flows and flows. All the others are properly working. Not sure if the accelerator pump affects it but it seems to be fine. is it the seat? I'm not to sure.

Any ideas please.

Can you get new seats for the 81 750k's?

Maybe your overflow tube is cracked, that is very common. Also have you cleaned the seat with a Q-tip and chrome polish?

Sorry, for some reason I had this image of someone polishing the vinyl of a motorcycle seat (the one you sit on) with a Q-Tip.

And yes, my "overflow tube" has been cracked for quite some time. It happens when you get older, so watch for it.

Ha, thanks! There is a hairline crack on the overflow tube. Do you have to replace the entire bowl?
