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!

Wonderful Knew you could do it!

I went the long way around on this one
But know how change a governor now! haha
Now need to see if i can adjust everything to get engine to smooth out!

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?

Somewhere in the back of my mind I remember that for the ignition module to function both wires must be connected to a spark plug. yet the service manual does not specify.

Does your engine have points or is it magnatron
Note the trouble shooting paragraph and illustration below.

If someone can say I'm wrong -- please do so.


With spark plugs installed, attach a #19368 ignition
tester to each spark plug lead and ground the other end
of the tester as shown in Fig. 8. Spin the flywheel
rapidly with engine starter. If spark jumps the tester
gaps, you may assume the ignition system is functioning
satisfactorily.
