I suspected such.
Your low idle issue right now is with the mechanical linkages and not the engines governor. First: You are going to have to get the linkages to go to idle without the governor. Something is wrong not giving you complete low end idle travel as it should?????
You might try disconnecting the throttle cable from the throttle plate and move the linkage manually back and forth towards low idle with the governor disconnected or loose on the shaft.

Does your governor lever arm look like this one on ebay?

Messing with linkages getting close idle is rough!

Ok new problem
Only running on one cylinder??
Found by accident
Pulled plugs to check them one dirtier than other cleaned it up a bit put back in and engine running perfectly!
Then I looked and saw forgot to put wire on the dirtier plug side!
Put it back on engine runs rougher!
Pulled other plug to test dirty plug side and no start! Engine turns no start!
So cylinder problem!
Maybe new coil?
Spark plug?

Ok its not the coil!
It did start on with just one wire on each plug individually?
