Shaw throttle linkage

I am kind of new to posting so be gentle...
I thought I posted earlier but now I can't find it.
I just brought home a 1951(?)Shaw R8. It is fairly complete and starts easy. It seems the last owner replaced the carb and the linkage on the throttle plate seems to be backwards so it defeats the governor. I can drive it but have be constantly feathering the throttle. It is an 8 HP Briggs, model 23F8C type 203540 serial #40705. Does anyone have a picture of the linkage on the throttle,carb and governor, a shot of a shop manual or a lead on where to get it?
Much appreciated.

Cant quite grip your terminology, do you mean the engine is racing out of control when you move the throttle? To hook the linkage up so the throttle operates backwards , I cant quite fathom how that could be done. If the P.O. removed the governor lever to disconnect the linkage, its possible the governor is simply out of adjustment. Loosen the pinch bolt on governor arm, and lift the arm with your finger so the throttle is wide open, and hold it there. Apply a screwdriver to the slot in the end of the governor shaft and rotate it in the SAME DIRECTION that you rotated the governor arm . Gently, it doesnt turn hard. All you need is your thumb and index finger on the screwdriver. If it doesnt turn, the governor is in adjustment (or the gear is broken) and nothing more can be suggested until you post some pictures of your governor system, as there were a couple different options available. There was a variable speed and limiting speed. Not knowing what a Shaw is, I couldnt even guess what you have. The limiting speed gov was used on vehicles like the 3-wheel postal trucks where the throttle was controlled directly by the operator , until the maximum speed allowed by the governor. The variable speed was for most other off-road applications.
 
Throttle should adjust spring tension something like this

Thanks for the reply, it seems to me the lever on the throttle plate shaft is 180 out. As the cable moves out it shuts rather than opens. At any point in the travel the cable keeps the governor spring from moving the linkage. I will post some pictures tomorrow. Thanks again.

Lesser known is a good place to post but has very little traffic. A post can go for months without any replies. So posting here is also a very good idea. As far as the tractor I know nothing about them except I would like to have one.
