Honda 95 xl250r starting problem

[tristo]

Hi all. I’ve pulled out a xl250r from god knows where, I’ve cleaned out the carby and put it back in. I’ve come into a problem where it’s wanting to push fuel into the air filter. First time working with a carby. Anyone able to lead me in the right direction?

Looks like the fuel is leaking through the idle air port. Remove and disassemble the carburetor. Check the float height and make sure the float needle is not stuck open. The location of your leak suggests that the float needle is stuck, overfilling the float bowl and leaking through the idle air port.

Be careful to shut off fuel to the carburetor until the problem is fixed, else fuel could pass into the cylinder, resulting in hydrostatic lock.

Is it a metal or plastic fuel tank. My XL250R used to feed rust particles through to the carb and make it overflow until I put a new fuel tap plus and inline fuel filter in after cleaning the carb for the umpteenth time.

Stuck float or knackered needle valve.
