my pops bought this bad boy in '91, one of the best mowers ever made ...model c21zpr ....
anyway, out of the blue it has started where it sounds fine at low speed idle, but as soon as I move the throttle up it starts sounding like it's flooding... put it on the grass and it wants to die with any cutting...no power... i cleaned the air filter, swapped the spark plug, and pulled the carb and cleaned it and sprayed out every air hole I saw on thing...pretty much the same symptoms...what next ?

Check the banjo bolt that holds the bowl onto the carb. I learned the hard way that the ports in that bolt get clogged and cause similar symptoms like you described.
I had taken the carb off and cleaned it and still had the same problem. Brought it to a small engine mechanic and that was the problem.
Use some fishing line or copper wire to run through the ports on the bolt and clean it out.

What octane of gas are you using needs to be around 87. What 2 cycle oil are you using.
