I am having a weird problem with my 2003 250ex. I was riding it around all day the other day, it was running a little rich but otherwise fine. I parked it in the garage and it would not start this morning. I have pulled the plug, it Sparks just fine. It was black because it was too rich but other than that it looks fine. I don’t have a guage but covering the hole with my finger, it feels like it has plenty of compression. Spark plug was dry. Fuel is getting to the carb. Brand new gas, non Ethanol. I’m not sure what else could be wrong. I took the carb off and checked to make sure the float was not sticky and it was fine. It has a brand new carb kit so I wouldn’t suspect anything else to be wrong, especially after already having it running. I also turned the Pilot screw back to factory specs (1 7/8 turns from bottom). Air cleaner is new. Not sure what else to do. Anybody got any similar problems that have been solved?
