TE20 CARB

Hello all
I have a 1948 TE ferguson with a Marvel-Schebler TSX312
I am wondering how the throttle from the governor to the carb throttle actually works......
mine just seems to have no spring.....just kinda free flopping around????
the choke has some resistance to it which works good, but again the actually throttle is really
loose & seems like there should be some resistance like the choke side????
if you have any suggestions besides next option to buy new carb. haha
or is there a better carb suited forthis little tractor I should be using?

Thanks for reading & taking ur time as always.

With the governor linkage properly adjusted, the dash lever in the idle position, the throttle should be held firmly against the idle stop.

With the dash lever in the fast position, engine off, the throttle should be spring loaded to the wide open position.

If this is not happening, something is out of adjustment, and likely the governor is not properly controlling the engine speed.

I have replaced governor
the whole governor has a little play init......the bumper screw said to adjust till you fell it touch screw than turn in one turn....
I have detached all linkage to see if governor moves just sitting at idle......it really doesnt...at this point I am holding the throttle linkage against stop on carb in idle postion & it will run......but again its not hooked up at the carb or throttle linkage.
I was just trying to see if it would run or what.
Tractor will run but when all linkage is hooked up it & I move the throttle to carb it just wants to rev up......

The most common problem is getting the link from the gov arm to the carb set to the right length.

To adjust it, disconnect the rod from the carb to the governor arm. Set the dash lever about mid position. Back the bumper screw off so it's not touching.

Hold the free end of the rod back against the idle stop to control the engine speed. Have an assistant start the engine and stand by to shut it down if things get away from you.

Be very careful reaching in, you will be close to the belt!

Slowly and carefully start bringing the RPM up while watching the governor arm move back.

Note the position that the arm stops going back. That is the length you need to adjust the clevis to when the throttle is against the idle stop.

You may have to make this adjustment a few times to fine tune it. The travel of the governor is limited, that's why this adjustment needs to be right.

With that set, then set the max RPM.

Loosen the U bolt up above the governor spring. Set the dash lever to full speed. Start the engine and rotate the rocker lever until the engine speed is set around 2000 RPM, tighten the U bolt. Cycle the dash lever several times to be sure the speed repeats and everything is working as it should.

Only if there is an idle surging problem will the bumper screw need to be adjusted. That bumper is pretty useless, all it does is take away some governor travel, don't worry too much about it.

Something happened to the link...
Gov Linkage

thank you.......I am trying to purhase new linkage also
when I was trying to loosing my broke.......i soaked it, it was just old i guess

Thanks again

If you know where I can find both throttle & gov linkage that would be helpful too.....

Thanks again for your time.

thanks buddy

I have undone linkage from gov lever assy
control rod from carb
gov lever arm rod also

have backed out bumberscrew also

I can start tractor while holding control rod from carb.....than idle tractor up & hold so gov would move back......the gov does not move at all??
not for sure but im thinking the gov assy should adjust itself back to idle like you said

not for sure what this means beside take this all apart again

Did you set the dash lever so the governor arm moved forward?

If the dash lever is still at idle it won't move.

There is no linkage going to the thottle at all......just saying
the throttle control plunger (unfortunately it broke while I was trying to adjust) is off
I did what you said & just manually held throttle from carb like you suggested

I got another one on the way.....

not for sure what to think about this......

Well, I think once you get it together it will work.

Here's the theory on how it works.

The spring at the bottom of the plunger, when you set the dash lever at high speed, that stretches the spring, which pulls the governor arm up.

That inturn pulls the throttle open.

With the engine running, the governor spins with the cam gear, which throws the balls outward.

The spinning balls trapped under the cone want to push the cone forward, which pushes on the governor arm inside the timing cover, trying to push it opposite the direction of the spring.

The governor is so designed there is a perfect balance between the 2 forces, the spring wanting to open the throttle, and the force of the spinning balls trying to overcome the spring.

The faster the engine turns, the harder the balls spin out against the inside of the cone, until they overcome the spring and begin to close the throttle.

The engine slows, the spring starts to win, opening the throttle. The engine speeds up, the centrifugal force of the spinning balls overcomes the spring and starts to close the throttle.

So, until it's all together it's hard to really envision how it all works, but it will.

Have faith! First one I tackled I had the same fear that something was wrong, but once I figured out the theory it all came together and worked like it should.

ok I will keep the faith........thanks for ur help again.....great explanation

FIRST ONE FOR SURE......lol
