SOURCE: 2003 WR250 F - eng. won't idle down and carb starts to overflow
Hi Jwelden,
Have you checked the float level in the float chamber?
I guess you may have to reset the float pin adjustment, its allowing more gas to pass through thn required and thus the overflow!
Not bad too, when you are working on the float assembly take the opportunity to blow out the fuel line from petcock to the carburator via the seat for the float pin,any foreign particals there would stop the float pin to seal up and thus overflow.
Fit in an inline fuel filter , this will help keep out the dirt or whatever.
Hope this helps.

see for that the float needle is fitted well, search for that any unwanted dirt or dust particle are not stuck in the flow line of fuel in the carbeaurator check for all port's & fuel line are clear inside the carbeaurator see what might help you out see you soon.....

The overflow problem is a carb float being stuck open. Turn off the gas and drain the offending carb(s). Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times doesn’t free the float I would remove the offending carb(s) and clean with a spray carb cleaner. By the way, Check the float, it could be filled with gas instead of air. Clean the air filter then re-mount carb(s). Next, remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an in-line fuel filter.
The lack of movement in the carb slide is either a bad cable or the the carb is a CV model. The slide on a CV carb will not move unless the motor is running. Start the motor. Does it speed up normally when you twist the grip? If so, then there is nothing to worry about.

your problem is inside the carburator.there is a small screen inside that needs to be cleaned out.take the single screw from one side of carb.there is a small screen in side.carefully take an air hose and blow it out.do not blow to hard or the screen will blow out.once it's clean the unit will start right up.hope this helped,let me know.................................
