we have a 250 that wont run right. it will start but dont want to idle then it will run ok for a little while 15 min. maybe then it will die. has new fuel pump, carb cleaned, rebuilt motor not too long ago, plenty of compression, i can barley pull the crank. any suggestions on jetting? any help would be greatly appreciated.
