Kz750 carb overflowing

I agree 100 % sorry I didn't see you wrote the same thing basicly.., Chance

Wondering if lack of combustion in #4 might be for some other reason besides a carb problem.

Such as ignition (eg., spark quality) or compression (eg., valve cleanance).

If not already done, would remove #4 plug and visually inspect spark quality.

While plug is removed, would do a compression test (remember to hold throttle wide open during test).

And for good measure, install a brand new plug.

If problem persists, re-address carb situation.

Good Luck!
