R Governer problems?

Start at the tank, make sure everything is open and you've got a good stream of gasoline flowing from the fuel line where you hook to the carb.

If problem still persists, open the carb drain and see if you have a good stream from there-some trash may have washed down the line and choked your needle valve.

One place I've had problems recently is the fuel bowl screen-assuming you have one. They can gum up with varnish, not flow much at all, but still look O.K.

When I first started experiencing the problem I took off the fuel bowl and screen and cleaned them out. I also drained the old gas and put in new. From there I went to the carburetor and had it rebuilt (which it greatly needed). I now get a good stream coming out of the bowl, fuel line, and carburetor drain.

Still, the tractor does not run well at high speeds (especially when in gear).

As for the throttle, there is no response from the governor or engine until the throttle is at least half-opened. After that the engine starts to speed up, then slow down, then speed up, etc., until it evens out and runs smoothly. Then, after a few minutes (or if you put it in gear) it starts to sputter and die.

Do you still think it is fuel delivery problems and not the governor or something else? I cannot see how it wouldn't be getting gas.

As always any advice is greatly appreciated.

Thank you,

If its your governor, you should be able to pull the link to the carb upward and the engine should rev up without any stumble or skip. Don't hold it long, wide open throttle on these tractors is what? 1400-1500rpm?

Somebody else can wade in on this thread anytime you guys want to.

Be SURE that your fuel tank gas cap does not have a blocked vent. On the carb. Freshly overhauled means nothing. I have rebuilt many carbs but get dirty fuel which eventually plugs up the main fuel bleed in the carb. This was even with a quality filter in the gas line.

Also, make sure that you do not have the governor linkage in a bind. By that, when you hooked up the carb. It is possible to get the linkage out of wack. I once somehow got my throttle in the wrong postion and when I hooked up the carb. I had no governor action at all, even though I could rev. the engine up and down with the throttle. That was on my UTU. Just a thought.

Lastly, you can check out the ignition system. IT would be worth changing all the plugs, wires and putting in a set of new points and condensor, cap and rotor. You can do all of that for under $50.00. Might be able to get a new coil as well. Chances are the machine needs it anyway. If memory serves me correctly the gap on the points needs to be at .020 clearance. I am assuming that you have battery/distributor ignition and not a magneto.

If you have good spark, good clean fuel and still have trouble, then check out the governor. You would have to pull it off the tractor. Take off the bottom cover and look at the internals. Alot of them get some slope inside of them and will not work right. You can usually pull on the throttle arm of the govenor some to set some tension and then spin the gear at the end and you should see the fly weights pop the linkage arm going to the carb.

If you have a worn out Governor. There is a guy in Kokomo, Indiana that can rebuild yours. Motec Engineering. I do not have his number handy. I know his first name is Matt. I think his last name is Gall. Someone else probably knows for sure. I have not talked to him in a few years.

Good Luck,
