Baught this new in 79. 11,00 miles. Took the carbs apart 4 weeks ago to clean for the summer, took out the jets cleaned them all and replaced keeping in mind the amount of turns on the high end jet. Both jets squeeky clean. Fired right up but will only run on choke. Push it in motor stops. Will not take any kind of throttle just dies. Anybody have any advice. Air or Fuel? And what it could be. Thanks
