Default Re: fuel line

The float, float needle, and needle seat are responsible for controlling the proper fuel level inside the carburetor. The fuel hose only provides a path for the fuel to flow between the fuel tank and the fuel inlet on the carburetor.
A new, larger fuel hose will have no affect on carburetor performance unless the old fuel hose was too small to provide adequate flow volume.
So wrong would be the answer.

If the float is adjusted too high it will raise the fuel level inside the float bowl and this can cause a rich condition.
Also if there is any debris caught in the float needle valve between the needle and seat the valve can no longer stop the fuel flow when it reaches the proper level. This too will cause a rich condition as well as flooding and overflow when the engine is turned off.
