I just purchased a 2004 lf250 which has 242 acutal miles and never titled.   It was used as a demo and left setting with fuel in it.   I have run it about 500 miles with lots of carb cleaner and it is just about smoothed out.   However as the weather is getting cooler in TN it is still will not set and idle smooth.   I assume there is a air/fuel adjustment screw somewhere on the carb but I am not having much luck finding it.   I am also looking for a shop manual for this model.  The owner manual was sent to me on line but no real detail on the carb or anything else.   Any ideas on where I can find this info?

Not sure how this posting is suppose to work but here goes.
