I need to know the correct length of the linkage rod from the carburetor to the governor arm on the left side of the tractor. There aren't any WDs around here to look at. Thanks!!! Farmer Pete
 
I do not have a WD but I have a W Speed Patrol which has the same engine so I went out and measured it. It comes out to be 12 inches or 1 foot which ever you prefer LOL
 
The correct length for that link, and for many engines, is for the governor arm and the throttle shaft/plate to both be wide open at the same time, or almost. You don't want the throttle arm being slammed hard against the stop every time the governor snaps open. That's why I say almost.
The only adjustment on those engines is to bend the vertical part of the governor arm.
 
With the engine off, pull the hand throttle wide open. Remove the cotter pin on the carb link rod behind the generator. Pull the carb link rod out of the vertical governor arm. The carb link rod length should be just long enough to slide right back into the hole without moving the vertical arm. Instead of bending the vertical arm, just bend the link rod in the middle downward until it's short enough to fall back into the hole. Also make sure your cotter pin on the carb end is cut off short and wrapped tight so it cannot snag onto anything and cause the linkage to stick.
 
Someone, not naming any names,(me)ha ha, saw a bent linkage rod and thought it was supposed to be a straight rod that was damaged. Because the WD has been apart for so long I forget some things. Thanks for this site. Anyway I'm learning a lot!!!
 
It doesn't make a whole lot of difference which is bent or which is straight(within reason) as long as the gov. and carb. are both wide open at the same time. The point of my response to DrAllis is that you have no choice but to bend the vertical gov. arm, if the link is too short.
 
I'll be working on my WD tomorrow so I'll measure when I'm out there. I've got to put the carb back on anyway, and change the starter out.
 
That is true, if it is too short. I can't remember ever having one too short. They are usually always too long.
