Governor setup TO35

As part of last year's overhaul, I replaced the governor, the old one of which was busted and has never worked in my ownership.

Well, I got the first chance to test the new governor yesterday and it's not working either. I followed the procedure in the manual but feel like I'm missing something very fundamental in the process.

Anyone have any good tips/troubleshooting advice? I'm fairly confident that the new assembly is intact...how can I tell if it is doing anything? Anyone have any photos of the linkage so I can see if mine is in fact correctly set up?
 
Hey friend, I just thought I would throw this in. The governor on my own TO35 doesn't respond nearly as well when the power jet is adjusted too lean. Have you adjusted your carburetor or checked it out recently? If this is the case it may start easily and seem to run just fine but then bog or slow down when the governor should kick in.
 
If you need the info to reset the engine governor and just what else you may need to check, email me and I will send it....John
 
If you run the mixture too weak then it can't open up the engine although the governor may be working correctly. To check the Carb is set correctly, you should get the engine to working temperature (not nearly) and open the throttle quickly, the engine should seed up immediately without hesitation or black smoke, if it hesitates it is too weak and needs opening up on the main jet a little more, if it throws out black smoke it is too rich and needs the main jet screwing in slightly. Adjust the jet about 1/8 turn at a time and then check it. All this is assuming that the electrical side of things, (timing and gaps) are correct. They need to be correct for it to test properly.This is simplifying it all but they are the basics of setting the Carb....John
 
Sorry, all, work has been a bear the last couple of days. I appreciate the offers of help.

I do need to thoroughly check the timing and the carb settings, that would definitely be a good first step. One thing that puzzled me when I was putting the linkage back together is that the adjustable part of the link between the carb and the governor lever is out on its very very very last threads, I couldn't have it further out if I tried.
 
Well, I spent today burning myself severely on the exhaust manifold, I mean, getting the timing and carb dialed in. I have the timing set and the tractor idles reliably at 500 RPM, which is about as low as mine seems to want to go. It does pick up right away on throttle without smoke or hesitation, so I think that's OK.

I followed the manual and the procedure John was kind enough to send me, and still nothing it happening with the governor. When I was fooling around with the idle setting, I did see the governor lever move as I revved the engine (control rod disconnected), so I do think the actual governor is working.

I took time to follow the book procedure for the TO35, up to and including putting the tractor in 3rd high at 1000 RPM and letting out the clutch to observe movement, when, of course, there was none. I have the bump screw completely backed out at this point, no difference.

Do these look like "typical" setups to you guys? This is with the throttle at idle position:

When I bought the tractor, the generator strap was bent behind the mounting ear with the governor connection in front of it. As far as I can tell, the way I have it now is actually correct, right?

I'm kinda stymied at this point. Now that I'm sitting here thinking about it, have I made any genuinely fundamental errors? As the throttle is opened, the control rod is moved forward, right? Is it even possible to assemble the throttle assembly on the carb backward? Idle is up on the throttle control on the dash, and you pull it down for more throttle?

The only model I had to work from is the way this tractor arrived here, and it all works well enough except for the governor.
