2 questions: Hydraulic leak and new carb, 1950 8N

Also since I installed new carburetor, I cant run at full throttle. The throttle lever springs back to about a little more than half when I take my hand off it. Is this normal? Do I need to adjust governor somehow? Thanks guys.

First either drain the oil or put the front of the tractor about two feet lower than the back by driving it into a ditch etc.

There are a couple of ways to replace the PTO seal. If you are pretty good at installing seals without damaging them in the process you can just pull out the old one by using a sharpened center punch to punch a hole in the old seal and then turn in a sheet metal screw into the hole and use a pair of vice grips to hold it and pry it out this way. Replace the new one with a piece of pipe just smaller than the outside of the new seal or what ever way you usually do it.

The other way is to drain the oil or put the front of the tractor into a ditch etc so the oil is not at the seal and then pull the PTO shaft. After the shaf tis out you will see a retainer ring behind the bearing. Remove this ring and then all you have to do it drop the PTO shaft driven end and assembly hard onto the floor or a big block of hard wood etc and the bearing and housing along with the seal will fall of the shaft. Then it is easy to drive out the old and install the new seal.

Search for "throttle quadrant lever ball" and you'll get some pretty good hits I think.
