47 Model A still won't idle, and runs to fast!!

Wes

I don't know how new you and the tractor are to each other and don't want to insult you but are you sure it's previous owner did not double up the throttle springs or put a rigid piece of steel against the spring? I've seen both and they'll cause the runaway you describe. There should be only a single leaf spring.

With the tractor not running, push the throttle lever all the way forward. Like an earlier post said, make sure the throttle rod is 1/2 the diameter of the rod shy of dropping into the throttle shaft hole when both the throttle and the throttle lever are in the wide open (WOT) position. Some governors are VERY sensitive and will have trouble returning to idle speed if the rod is more than 1/2 a diameter short! Since you're having trouble slowing your beast down, I'd suggest setting it so that the rod drops straight into the hole instead of being a half hole short until you find your trouble.

Anyway, connect the throttle rod. Pull your throttle handle all the way back. The governor spring should touch the point of the governor lever arm and the carb should be at or near dead idle. If not, adjust the throttle handle's idle stop bolt to allow you to reach this point. Next, advance the throttle lever ahead from dead idle until the carb just reaches WOT. The carb should reach WOT before the governor spring starts to leave the point of the governor arm. At this point (tractor still not running) you should easily be able to move the carb's throttle shaft from wide open to dead idle by fighting only the fairly light force of the governor spring. If you can't, then like someone else said, you have a governor problem.

If you start the tractor with the throttle handle still in this position (spring against or just barely pulled off the point) the governor should almost immediately increase the distance between the point of the governor arm and the spring in its attempt to slow the engine down and the tractor should run slightly above normal idle speed. If it still races, like the other guys said, you have a governor problem. I've seen stuck thrust bearing sleeves, bent or broken governor lever arm shafts, stuck or broken weights and many other problems. If you adjust and test like above and it won't work right, you won't necessarily know what is wrong but you'll know the trouble is "inside the box"!

Good luck and let us know what you find.

Later.

Your gov weights may have gotten tucked behind the thrust fingers that operates the shaft thatoperates the gov control to the carb. Or something may have come loose in the gov housing.
Anyway take the cover off and look.Remove the mag before re installing cause the coupling may not lign up and you will push the shaft out through the mag.and ruin it.
