kylemorley 09-09-2012 09:23:40 96.61.92.35 Report to Moderator	While trying to troubleshoot my 8n's reluctance to accept a load, I notice that the governor, while passing most of the informal tests that have been mentioned here, at the lowest setting of the throttle lever makes a high pitched rattling noice - sort of a she-e-e-e-e-e (never gets to the t), like a handful of birdshot being swirled in a metal container. At least I think it is my governor, I suppose it could be elsewhere but seeing as how playing with the throttle makes it come and go I am pretty sure. Oh, I also notice that I have to open the throttle 1/3 or the way before I can detect any increase in speed from the motor (tractor standing stil). Is this normal, or is my governor trying to tell me something. [Reply]   [No Email]

They came off a 1948 8N. Just rebuilt my governor to find out that the governor was ok and the carb to governor linkage was not the correct length. Bruce assisted with finding the correct linkage length. New kit costs about $80.00. Let me know- mechanic that took the governor apart suspected linkage problem! Mr. T. Minnesota [Reply]  [No Email]

One of my vices when it comes to machines is that I hate to waste new parts when servicable old parts will do, so, since it is looking like my governor is going to need attention, I'd be delighted to acquire some hand me downs. Let me know what you want for post etc. You can email me at kylemorley66@yahoo.com. [Reply]  [No Email]

There are marble-sized steel balls in there which will rattle like that. " while passing most of the informal tests that have been mentioned here," Such as? " I also notice that I have to open the throttle 1/3 or the way before I can detect any increase in speed from the motor " Hmmmmmmm......... Lack of low speed throttle response. Doesn't that tell you something? Try some of these tests.......... There are three ways to check to check the operation of the governor. Get the throttle lever at it's lowest point (engine ideling) Then, start tapping the throttle lever slowly open. How far does the throttle move before the engine speeds up? Lack of low speed throttle response (like about 1/3 of the throttle) is the classic symptom of a bad or out of adjustment governor. Next test, put it in gear at about 1/4 throttle, put your foot on both brakes & let the clutch out. The engine should throttle up as the governor arm opens the throttle plate in the carb to compensate for the load on the engine. Next test, w/ the tractor running, pull on the rod going to the carb; does the governor pull back? If that does not work, get out the I&T FO4 manual & check out the 'adjusting governor' paragraph. Finally, before I paid $200 or more for a governor, I'd pull it off & open it up. It could just need new balls & races. 50 Tips [Reply]  [No Email]

I originally did them a couple weeks ago and everything seemed fairly OK. However repeating them just now, I find: - the revs don't increase till the throttle is 1/3 open - pushing on the throttle rod makes the governor push back. -when I let the clutch out while holding the brakes the governor does not seem to be doing much, and unless I give it gas manually (or often, even if I do) it kills the engine. I blew out the carb one more time and checked fuel flow from the plug on the bottom of the carb, which was steady. So I think it is probably time to pull the governor. [Reply]  [No Email]
