1947 B, 12v conversion. I solved the spark issue yesterday and the carb has been done. Battery fully charged, static timing set. Scratching my head over why it won't start when I got the idea I had not pulled the valve cover and checked clearances. Found two push rods loose on two different cylinders. Got them back in place but when I rotated the engine the third from the rear valve went down and did not come back up. Gentle persuasion in a couple forms failed to get it to pop back up. SO....looking for some advice.
This is deeper into the engine than I have gone in the past but I am game if that is what it takes. Is there any hope of unsticking the valve without pulling the head?
If I pull the head it looks like the rocker assembly comes off with three nuts, then there is the coolant connection on the front and the manifold(s) on the side followed by (5) large nuts down the center of the cylinder head. I apologize but apparently I never found a parts manual for this tractor so I am going by what I see. Not sure what makes a valve stick but I'm not thinking there is anything terrible wrong here...hopefully. All guidance, suggestions, and commentary appreciated.
