Look at the throttle assembly on the carb. From idle to wide open, the throttle shaft needs to turn approximately 90*.
Now start the engine, set the speed for low idle where the throttle is against the idle stop screw.
Then suddenly push the dash lever to full speed and watch the throttle. It should go to full wide open for just a second, then return to maintain the governed speed as the engine comes up to speed.
If it doesn't go fully open, the GOVERNOR LINK needs to be adjusted.
Also check that the engine runs at 3600 RPM (or whatever the book calls for) when at full speed. If not, the GOVERNOR SPRING needs adjusting.
You can play with the linkage with it running. Have it running at full speed, push the throttle closed and release when it gets to idle. It should instantly spring to wide open, then govern back down.
You can also watch what happens under load. Have the engine running at any speed as long as it's well above idle. Put a load on the engine, as in engaging the PTO. The throttle should go to full open until it reaches the set RPM.
