Day two and she still purrs along at anything above an idle. Got that hiccup back here and there but it lessens when it warms up. I cleaned the screens and they did have a little crud in the sediment bowl screen. Managed to get one of the fuel line connections leaking....a personal curse that follows me from tractor to tractor. Not many people can crossthread a brass nut as easily as I can. I also played with the idle screw a little when the screens failed to solve the problem. The idle screw turned either way did not seem to have much effect on the idle.
So here is where I am standing. Good strong running tractor above idle. The idle is fairly rough and can even stall out the tractor. The throttle lever only seems to affect operation when it is forward of 90 degrees. Straight up and down is idle. Pull it back further and nothing happens. Push it forward and it throttles up. I have no smoke or hesitation. It has a Zenith carb. I have read both manuals regarding the idle and governor but don't really have the smarts to identify what might need work.
I would like to fix the idle and, if possible, get a throttle that operates the engine speed thru it's entire range. Need help! Thanks guys!

We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
