.......Have a ZR-7 carb rack set sitting in my garage. Those holes do not have balls or any plug. That is the starting jet passage. I have bench tested these carb rack in a bench and if needles are proper size, and level is just slightly about the seam, they do not leak when filled by fuel.

If you are sure the needles are proper size, (many needles look same but they are not, ....specially aftermarket), .....then I'd drop the level some. Use the wet U-tube method to check where the level is. Don't rely solely on the dry float height method.

...never heard of floats becoming heavier....It they did, it could only happen by build up, which would be rather insignificant. Even if real, which I doubt, you could simply drop the level to compensate.

My question;.................... do you really know where the level is????
