Why is my 2005 CRF150F not idle?

How do you remove the jet from a carb?
Disconnect the main jet from the needle jet holder using a small crescent wrench and a 6mm socket connected to the 1/4″ ratchet. Connect a 7mm socket to the short extension. Using your fingers, use the socket/extension to screw the needle jet holder back into the bottom of the carb until it’s snug.
What to do when fuel dribbles out of CARB?
Use the open/box wrench to loosen the cap on the bottom of the carb float bowl. Use a rag to sop up any fuel as it dribbles out. Don’t let any fuel reach the engine or pipe if they are hot from recent running. Unscrew the cap with your hands, being careful not to spill the fuel in the cap. Inspect the fuel to see if there is any water or debris.
