I've been working on this tractor on and off as I use it. (And having a great time!) I have an 89 Tempo, a 91 Ford CV and a 93 F150 and compared to those, it is a joy to work on this old tractor.
I R&R'd the carb and then tried to set the linkage between the carb throttle & the rockshaft arm. With full throttle position using the throttle lever and the carb connecting rod all the way back for WOT (wide open throttle), I removed the yoke pin and found that the pin "holes" missed each other by almost an inch.
The problem is that in order to line them up, I have to turn the yolk towards the carb and there isn't enough thread to go as far as required.
I can't imagine that it should be this far off without something else being wrong.
A couple of thoughts:
Can I loosen the rockshaft arm from the rockshaft and move it away from the carb to get the adjustment? From the diagram I have it looks like there's a pin or something that sets the relationship between the two. Unless it's been broken off.
If not; does this mean that the rockshaft lever inside the gov or the gov thrust sleeve and bearings may be bad?
All linkages work freely including the throttle plate at the carb and it "feels" like all the gov bearings/bushing are tight and the rockshaft/arm rotate to a solid stop in either direction.
Thanks in advance for any advice on this.
Oh yeah, it runs great other than a surge at idle which once I get the carb/gov linkage problem solved I'll check the bumper spring setting.
