I have a wd and the problem i am experiencing is when i fire it up it runs wide open. I shut the tractor down immediately because i know this is not right. I am assuming that there is a problem with the governor. Does anyone know the proper adjustments of the governor or have a diagram of how it should be assembled. I have searched different places on the internet but have not been able to find any info on how i should fix this problem. I would appreciate anyone knowledge.

need to pull the gov sounds like the weights have broken off . this is what caused me to rev my puller above the rpm range I had it set for. With the tractor off the throttle pulled wide open the carb should be wide open with the carb rod being about a half the hole long meaning the cross shaft needs to be pulled back towards the radiator to preload the gov. I think the measurement is a 32cnd

weights unit, remove two nuts and
cap screw which retain magneto or
distributor bracket to engine and withdraw
bracket and shaft gear and
weights assembly as a single unit. The
weights and trust bearing can be renewed
at this time.
If shaft, gear, or bushings require
attention, the shaft should be removed
by bumping out the drive pin (28—
Fig. AC52G) on magneto equipped
models or remove distributor unit
drive gear on battery ignition models.
When bumping out the pin, be sure to
prevent bending of shaft by bucking
up same with a length of pipe introduced
through the opening in the bottom
of the magneto drive bracket.
On the WD, WC and WF gear (17)
is sold only with the shaft assembled,
not separately. To avoid damage to the
shaft when removing the gear, cool the
shaft while heating the gear. Shaft
should have .002 running clearance in
bushings.
It will be necessary to remove the
timing gear cover if the governor
throttle shaft and cross shaft are to be
overhauled. With cover removed, check
cross shaft bushings and, if necessary,
renew same. Check governor lever
spring eye holes jind contact surfaces.

i got a carb back from rebuilder and fired up and went wide open. He changed the throttle plate inside and linkage was backwards and I didn't catch it. Nothing like a new engine going sky high right away!!
