I tried the archives but could not find anything on this and I remember about 2 months ago someone else had the same problem. When we are running the 48 8N the throttle keeps snapping back to about the 1/2 way mark when it is opened up. I plan to do the following to try to correct it:

1. Remove and clean all of the linkage, especially from the throttle to the govenor making sure that everything is clean and in good working order.

2. Check all of the springs and make sure that nothing is out of place.

My question is-could this be a symptom of the govenor needing attention? Possibly a rebuild? It happens consistently and gives a good solid tug-you really have to hold it in place to keep it full throttle.

Is there anything that I'm missing?

As always, many thanks!

Adjust the tension like the others have suggested.

I started out with the same problem you had.

I also took the little ball bearing out of the under side of the throttle lever and put it back with a fresh face toward the plate. That and having the tension (adjusted at the lower end of the rod) set correctly made a world of difference.
I would have replaced the ball but didn't have one that size handy.

N - joy.

Gee, do not mess with the governor, this has nothhing to do with the gov. You may need a new throttle position plate, (About $14.00) They wear were the ball rides on the plate. Plus as mentioned before, ensure that the spring tension on the throttle arm is set at max...Try not to make a $50.00 job out of a $5.00 job..
Happy Motoring

I will try to explain this. I don't have my manual in front of me so I may not use the correct name for the parts.

If you notice, the throttle quadrant and lever work together. There is a ball in the lever and notches on the quadrant. The notches hold the ball and the ball holds the lever in the position you want. Follow?

You can adjust the down pressure on the lever, which will increase down pressure onto the ball into the notches. Look at the throttle lever rod that goes through the dash and attaches to the rod that goes to the govenor.

There are I believe 2 bolts. Loosen those and pull down on the throttle lever rod then tigten. This should do it.

Hope I was clear,

Ron

That is what your Govenor is supposed to do hold it at a set speed. When you open it up by hand the govenor will try to slow it down so you do not over rev the engine. The carb will be pulled open by the gov as needed for more load put on the tractor engine to keep the RPM the same. Check to see if you can get max rpms out under no load. Is the throttle control arm below the wheel moving back from full throttle? Mark H.

It happens both under no load and loaded conditions. It looks like all the linkage from the govenor to the throttle is snapping back. I sorta suspected that the governor might have that level of control and given what you've told me I suspect that if I rule out the other causes the govenor is gonna be in for a rebuild.

Time to dig out the F&O manual!

(Not this weekend though-I'm gonna give the Power Wagon a tune up and start making a list of things to do before I paint it!)


Thanks Mark!
