Hello, new to this forum, and first post here.
Short background: I?ve spent the several weekends over the past few months trying to get an old family John Deere 620 to start. Last weekend I finally had success and got the old tractor to fire up. I?ve fought fuel, ignition, and compression (stuck valve) problems along the way.
I can now get it to start, and it will run at idle, and if I very slowly advance the throttle, I can get it up to what I would consider ?fast idle.?
However, if I attempt to advance the throttle more, or if I attempt to put any load on the engine (like driving), the engine will stall out and die. If I pull the throttle all the way back to the idle/choke position, I can ?catch it? and keep it from dying completely. However, I am unable to get this machine to make much power at all past idle.
It seems like a fuel delivery problem, but I cannot figure out where or why. I?ve gone through the Century M regulator, I?ve cleaned the carb as best I can (it had a fair bit of rust inside the body).
Anyone with propane tractor experience? I?d love any help or suggestions. Thanks! Jeremy
