Now that I've fiddled with everything else on this tractor, I'm looking at how it runs fully loaded.
Why? It just has this feeling like it's holding back at full throttle.
First, timing. My understanding is that, for the 2N with front distributor, the only timing adjustment is done for "static timing," that is, when you do the straight edge to mounting hole measurement and set it to 1/4" when the points are just opening.
The F0-4 manual says that timing should advance at full throttle above 2000rpm.
Since there is nothing in between those two sections in the manual, I'm assuming that the advancement is done by the "advance weights" in the distributor automatically?
So, I'm assuming that there is no adjustment to the advance. It's just something that could possibly be measured to see if the advance weights are working? Right?
Now, governors:
When I throttle the tractor down to idle, the throttle lever on the governor hits a stop and forces the governor lever (the one actually connected to the carb) forward, which forces the tractor down to idle.
At that point, the governor spring goes slack, and moving the throttle a little ways does nothing, until the slack is taken up and the spring starts to pull the governor lever forward. Even when the slack is taken up, the spring stretches a little bit before actually moving the governor lever.
When I go to full throttle (with the tractor sitting still) the governor lever initially goes to full throttle, but then the governor stretches the spring and the rpms diminish. I assume that this SHOULD happen, but when I put the tractor under load, I just get this feeling that the spring isn't pulling the governor lever back to open the throttle back up.
Here is where I wish that I had my brother's old grinder/mixer to connect the tractor to; so that I could hook up the pto and have someone run a few shovels full of corn through so that I could stand and watch the governor's response. All I can do is "feel" it when I climb a hill with the tractor to test the throttle response.
Any hints on how to test this....or should I just buy a new spring and see if it changes?
