Still Having Problems

Ok, so I rebuilt the carb, replaced the governor, and tuned up the 2N, plus replaced the head gasket, and it still over revs, what should I do now?
 
Sorry but I'm not much good with those Ns.
I will give you some general advice though.
Stop throwing parts at the tractor and find out what's wrong with it.
Then you can fix it.
 
Did you remove the throttle shaft and throttle plate when you did that rebuild??? If you did then did you get it back in correctly and did you put the throttle shaft back in correctly??? Does the linkage bind in any way?? Is the throttle control hooked up correctly??
 
disconnect arm from governor to carb.. can you manually control throttle function at the butterfly

did you get all the connections to the right spots?
 
If you are saying that it starts at full speed?
It is almost certainly the carb or linkage.

The throttle plate is there to regulate the air
flow. It is mounted to a cross shaft. The shaft
is offset for the purpose of letting the throttle
plate which is bigger than the bore of the carb
(venturi) close against the bore because it can't
go past 90 degrees to the bore. Suction on the
throttle plate happens on both sides of the shaft,
so, since the plate has more area for suction on
the appropriate side there is constant force
trying to close the throttle.

It is possible you have somehow got the throttle
plate mounted on the wrong side of the shaft and
the throttle is being sucked open.

Give us some more detailed information, if nothing
else.
 
Everything is hooked up the same way as it was before I messed with it, and the same way it is on my 9N. I even tried the governor and the carb off the 9N, still with no result. Also, it's not that it runs at full speed when starting, it runs higher than it should.
 
Do as sound said then and take the linkage from the gov to the carb off and hold the throttle control closed. If it still runs way to fast you may have a vacuum leak in the manifold which can cause an engine to run faster then it should. If you can not slow it down by hand then you have a carb or manifold or other such problem
