Is my governor right?

dsebens · Feb 25, 2020

On my 73 3400 if I slowly bring my idle down it will idle at 1000-1100 according to the proof meter. If I give the throttle a blip or drop the rpm's quickly it will drop down to 650-800ish(I can't remember what exactly)

My linkage is free, is this a normal operation or do you have any ideas. It doesn't bother me too much since a blip can drop it down but was just curious.

My 2000 does the same thing. I never could get the linkage quite right. I think the problem is when the rod is set to the correct length there is a bit of free play between the bell crank and the plug inside the spring. If I adjust that out it acts differently. It's been a while since I played with it so I can't remember which way it worked but sometimes it would not hold the throttle at PTO speed under load.

I think it's more of a carb adjustment issue. If you're "blipping" the throttle, you may just have either a lean or rich condition causing the slow down and the reaction of the governor may be accurate, but with too much/too little fuel, you won't get the response you're expecting.

Do you get a puff of black smoke when you rev it?

Tractor runs good. When I blip the throttle it will stay at idle until I speed it up again
