    Deere 850 B no start.

    Kept soaking and a little gentle prodding with a flathead and it freed up. I see what you mean. There’s nothing to pry against that sturdy. Thank you so much!

    I can feel a difference in the throttle lever if I pull the fuel shutoff. I don’t know how the linkage is so I don’t know if that matters.

    I used to be in Walhalla. I’m near Greensboro NC now. I would take you up on that if i was in the area. And about the remote start. This dozer has a “feature” where if you push the start button it turns over till it fires. Or you hit the master shutoff.

    I got some Knocker loose and put it in the fuel galley and turned it over. Batteries obviously need charge and they got it right after this.

    So there's a magnet that holds the rack for starting? If I let it run at half throttle and move the throttle quickly to idle it will die. If I do it slowly it will not die.
