'36 WC surging when throttle increased and sitting in Neutral

I have done some research but wanted a second opinion. I have found many surging problems listed and they all revert back to a spring on the throttle rod in front of the Carb, and that there is a hole in the throttle rod for the spring to attach too, and then the other end is to attach to the petcock on the engine block. Now if the throttle rod on my WC does not have a hole can the spring just hook over the rod or does a hole need to be there, and does the hole need to be directly above the petcock, or is there specific positioning of the spring on the throttle rod? I should mention when the tractor is just idling it purrrrrs really nice and basically sounds good. The Carb has been rebuilt, and the tractor starts easy.

Thank You.

Surgeing on the 201 & 226 engines is usually caused by either a sticky throttle shaft or the govornor rod out of adjustment.The hole in the govornor rod for a surge spring was used only on the B&C 125 engines.THe length of the govornor rod is importment. To check with the engine not running pull the throttle lever wide open and then disconnect the rod from the throttle shaft. Then hold the throttle shaft wide open .There should be about 1/8 of an inch movement on the rod to make it go into the throttle shaft.Adjust this rods length to get this diminson.

The spring on the WD45 just hooks over the throttle rod- no hole involved.
