Quadrant/Choke Setup

I have a 1950 8N. I can't find out what are the correct setup/adjustments for the throttle and the choke controls. I realize the throttle quadrant's goal is to maintain a rpm setting irrespective of load. However, is the throttle quadrant supposed to be a "set and forget" control (you put it at a position/rpm and that quadrant lever holds that position in spite of the springs), is the quadrant supposed to return to idle (like your car's accelerator pedal you have to hold it at a setting for a specific rpm - I certainly hope not), or a combination of the two/something in-between? Let me ask another way: If idle is quadrant=0 and full throttle=100, I move the quadrant to 100 (I'm goosing it) and let go; should the quadrant (A) stay there/full bore, I have to manually move it back (B) get pulled all the way back to 0/idle or (C) come back somewhere in between? If (C), where should it be? (with all of these A,B, & C's and a few ='s, my high school algebra teacher is probably rolling in her grave right now)

Similarly, should the choke knob stay where I left it, retract fully, or partially retract? I'm a lot less concerned about this as I don't have a need to monkey with the choke once the engine is warm but it'd be interesting to know what it should be doing.

What did the "founding fathers" intend to happen? (Thanks!)

The choke knob is supposed to snap back to full open when you let it go. It is used for starting the tractor. On my 9N i have to hold the choke out a bit while the tractor warms up. (I use a spring type clothes pin to do that).

But... (there's always that "but") On my 1950 8N, both the throttle and choke are "option C", they partially retract. It is much more annoying with the throttle. When set to high speed (near maximum), the lever will immediately move down. Note that at a low throttle setting, it will stay in place. At best, it'll work its way down from a high throttle setting as I'm working (bouncing/vibrating around) and any kind of a high speed requires a hand on the throttle (well, quadrant lever).

So - with the throttle, am I correct in that it is only the teeth on the quadrant (mine are worn down a bit) that keep it in place? It's as if the springs (governor/linkage) are too strong for my quadrant teeth. Any thoughts/suggestions?

With my choke, it is as if the spring on the choke plate/butterfly lever isn't strong enough. There is no binding in the choke linkage. Should I get another stronger spring? Add a "booster spring"?

It seems as if it is always "too much" or "not enough". :)

Once again, thanks for the help.

You can pry and rotate the ball to an un-worn area and then re-stake the ball into the pointer arm. ...or... you can try and find a replaceable ball-bearing at the hardware store. Sorry, I don't know what size a ball it is. You can now get replaceable notched throttle quadrants. p/n: 8N-9889-A2, quadrant, throttle control; $15 (cheap)

As to yer non-returning choke strangler. There is supposed to be a "clock-spring" type that has little arms that are known for eventually breaking off. p/n: 9N-9539, spring carb choke retainer, $55c (cheap) You will haffta remove yer carb so you can find the spring hidden behind yer choke lever arm..... ....Dell
