3-53 Detroit governor

I switched the governor to a mechanical one on a 3-53. Engine starts right up but no throttle response. Only has a short run time head was removed and all injectors arms in the rack moved easily. I?ve spent way to much time on it to stop may have to try and make the other governor work anyway. My first Detroit experience and don?t have a manual for the engine or machine.
 
What is it to used for? There are two types of governors used ,a limiting speed for use on highway type vehicles and variable speed used for maintaining set engine speed and with variable loads such as ag equipment,saw mills etc.
 
You need to halt all operations and procure a shop manual for the 53 series. If you're swapping governors, an operators manual is not enough. Then, before you even open the book, inspect the emergency shut-down on your engine, try it a couple times, make sure it works, and if it doesn't, do nothing else to the engine until the shutdown works. Don't do what they do on You-Tube with vise-grips on the control tube, that's just B.S. The emergency shut-down is easiest to use and is the most effective way to control a runaway. The emergency shut-down does not ruin the seals in the blower, that's just MORE B.S. If your engine has no shut-down flapper, as would be the case with spring-loaded injector levers, have some part of the air intake system prepared so you can clap a board over it and cut off the air. I know you posted for help to get your engine running, not shutting it off, but you don't sound too handy around Detroit governors; if you screw up and don't get the pin to go through the little forked thing, you're in for a heart-rending experience that you will want to get under control quickly.
