Good evening: A question of what took place today when a JD 4020? was run out of fuel.
With the lower bleed screw (pump body) i got bubble free fuel within a few cranks,closed it and opened the upper bleed screw and no bubbles or fuel..?
Rolled it over a few more times looking for air, and it started to make white smoke/barked and started...
Still there was no fuel out of the upper bleed ?
Are you able to learn me why/how this happened ?
I can only think the upper bleed is blocked inside by dirt? and it self bled the lines/injectors as i rolled it?
As for running/power no loss noticed using a 6ft bush hog.
Curiously can kill the cat...on this one.
Tks for your thoughts

What injection pump does it have? DB, JDB, or the obsolete CB pump?

Today's Featured Article - Pop's Tractor of Gold - by Gary Teate. My father was a simple man but could repair just about anythin mechanical that was ever made. From the time I was a young boy growing up in Jacksonville, Florida, I would spend a considerable amount of time helping my father repair or rebuild equipment and engines, etc. on our 2 1/2 acre "spread". Pop always dreamed of having more acreage out in the country where he could retire and tinker as much as he wanted and often reminisced about his boyhood days on his grandfathers farm in Montecello, ...
