Throttle Lever on 9N

Hello, I'm new to tractors and recently bought a 9N. I have a question about the throttle lever.

When sitting on the tractor, the throttle lever is right hand side of the steering wheel.

Along with the lever, there is a type of plate that it rests on, and the plate has notches in it.

The extremes of the lever is either up or down.
Down is more toward the driver set, while the up is more towards the front of the tractor. This isn't exactly correct because the lever does not sit parallel.

In the down position, is this the idle or lowest RPM setting of the engine? And up position wide open throttle?
Any help would be appreciated. Thanks.
 

Thanks Royse. This helps greatly.
Reason I ask is because I stored the tractor for 1.5 years and didn't do any maintenance such as draining the gas out of the carb or shutting the gas valve off.

I had to rebuild the carb but having trouble adjusting it. Now that I know up is idle I can try to adjust the carb again.

Thanks much.
 
"I can try to adjust the carb again."

The I&T FO-4 manual has a pretty good procedure for that.
If you don't have one, turn the main adjustment needle, the
larger, down pointed one all the way in until it lightly seats.
Then back it off one and one half turns.
Adjust the idle air mixture screw, the smaller side pointed one
all the way in, then back it off about 1/4 to 1/2 turn.
Remember that this screw adjusts air, so in is to enrich, out for lean.
That should at least make it run. Adjust as needed from there.
 

Yes it starts and runs. Just that the carb isn't adjusted at the throttle idle and wide open positions. Now that I know up is idle, I can retry.

And yes, I'll look at the I&T FO-4 manual if I can find it.

Thanks again.
 
Welcome to the wonderful world of Ford N-Series Tractors -you're gonna have FUN! Your first order of business is to get the essential owner/operator, parts, and service manuals. Read religiously, SAFETY info a MUST -ya gotta know the do's and don'ts BEFORE you do anything. FACTS: All standard 9N and 2N models used the '9N' prefix in the serial number. There was never a '2N' prefix in the serial number. ALL standard 9N and 2N models used the 3-speed transmission and had only DRAFT CONTROL 3-PT hydraulics. ALL 9N/2Nmodles after s/n 12500 used the same basic electrical systems and ALL FORD N-SERIES tractors were 6V/POS GRN setups using the front mount distributor, a generator, and the round can cutout. Be aware that many were switched over to 12V systems along the way. There is nothing wrong with a 12V system -many N's have been changed due to old, worn out engines that are not capable of being rebuilt and so need faster spinning starter. Also be aware that many electrical systems are not wired correctly regardless whether 6V or 12V. That is why it also important to have the essential manuals. You can search for John Smith's Tractor ID/History web site page, now archived for more info on tractor models and parts. Serial numbers do not mean a whole lot, unless you have an early 9N that you will be restoring, or an early 8N. There are some mutts out there -tractors that had blown engines and then got replaced with ones from other tractors so again, the s/n is not an absolute defining factor. What is important to know is: Front Mount Distributor; 6V/POS GRN or 12V/NEG GRN; Electronic Ignition added; having the correct wiring no matter which setup is used; 3 forward/1 reverse speed transmission; Draft Control (9N and 2N only, the 8N had the additional POSITION CONTROL as well); just to mention the major components.

Hi bennenshaw, welcome to our little world of early N tractors. Be sure you have the linkage hooked up correctly. The lever from the governor goes to the throttle link on the carburetor and the link from the choke goes to the choke. I've heard of folks reversing those.
 
Yes, to answer your question, but if you can, start the tractor, in neutral, and the simple throttle up and down movement will tell which way increases and which way decreases to idle. Are you having issues?

Hello PloughNman, Thanks for the advice about getting manuals. I agree and will start building a library of such.

Issues? Yes but things are getting better. After having the 9N stored for about 1.5 years and not starting it during that time, it had difficulty staying running. So I rebuilt the carb.

After rebuilding the carb my memory told me that the throttle level was down for idle and up for full open throttle. Yet in adjusting the carb I couldn't get it tuned correctly.

So I am on here asking the question about throttle level. Royse says my memory is wrong and that up is idle. With that knowledge I can fine tune the carb.

A word about what I found online about tuning the carb. Everything says about the same - to do a factory setting of the idle adjustment screw, and the main adjustment screw, of 1 or 2 turns out from fully being in.

They go on to say that after the tractor is running, to fine tune the two adjustment screws while listening to the motor.

What they don't say is what to do with the throttle while fine tuning the two adjustment screws. Or maybe it is given of what a person should do.

Talking with a neighbor, he says to move the throttle level towards idle (up) while adjusting the idle adjustment screw.
For the main adjustment screw a person needs to move the throttle lever down to wide open.

With this knowledge I expect to fine tune the carb.

So yes I was having trouble but things are getting better.
Thanks again for all the assistance and well wishes.
