Blown Away

well its an 05 crf150f all stock. bought her from a friend for 100. yes thats two zeros not three. put her all back together and started her right up. i had been riding her for about an hour when in the middle of a little burnout (raining with mud) she died suddenly. she still wont start and its been about a month. gas is squirting out of the carb from the bottom hose and when i took off the carb it was full of gas,like completely full. ive out on a new carb and checked my timing ut its still doing the same thing. Maybe a valve is stuck or idk. any ideas would be much appreciated!!

If fuel was running from the vent tube, then it sounds like the float may be stuck. Pull the carb. (Don't forget to count the turns from all the way in on the mixture screw) Clean. Spray carb cleaner through all passages. Blow compressed air through all passages. Put it back together. New spark plug. (If float was sticking, the old plug is most likely fouled.)
Should be good to go.

that was the first thing i checked. the floats were fine and the jets were undamaged. as i said i just bought a new carb. thankyou though

Im to PRO

i think "she" may be done. lol i have no clue. you said you cleaned the carb? i would take it apart and tighten all the jets and bolts in there to make sure its all good

There should not be fuel running from any of the vent tubes unless the float is set wrong or something is wrong inside the carb.
In the mean time, go ahead and check the plug to be sure it wasn't fouled.

plugs good. its a new nkg plug and its gapped and sparking fine.i wonder if it has something to compressionbut im still leaning towards valves. i think its time to visit the honda shop for a diagnostic. expnsive but well worth it in this case.
