Most excellent!!!  
 
Re the throttle, they'll be at least one cable from your throttle down to the engine.
They'll be one bolt (likely a 8mm /  5/16") clamping down the cable.
 
Loosen the screw and push or pull the cable just slightly till you see the throttle close on the carb
(while the control is in the idle position)
 
Some machines have the choke and run cable as one, yours likely does.  Don't go too far or the choke won't close fully.

Any updates?

Yes. I had to make a very slight adjustment to the governor lever in relationship to the governor shaft. You may ask why? Normally you don't need to mess with that. True, but I also replaced the governor shaft oil seal and I thought I marked it carefully before disconnecting, but maybe I was just a tad off. Now engine runs just like before. Now the good news. After mowing about 3 acres (not all at the same time) it looks like the oil problem is solved. Piston rings it was, I am pretty sure now. That was exactly what you suspected from the getgo. It used a little bit of oil, but I attribute this to the fact that the engine needs to go through the brake in period and find its sweet spot.  I assume after everything works itself in I will have a good engine with little or normal oil consumption or maybe none. Thanks again for all your help.

Glad to hear it!
