1983 Lawn boy won't run properly

I have a 1983 2 cycle 21" Lawnboy that won't run properly. It was stored for about 5 years and initially wouldn't run at all. I checked compression and got a reading of 90. I then bought a new carb, and, with starting fluid, it began to run, but always dies under load. My wife says "Throw it out!!" but it was a "sweet cutting" machine before and I wonder if I should give up, or maybe replace the underdeck muffler. Could it be clogged? I have also installed a new primer bulb and hose, new wheels and blade.

If you've never puller the muffler under it and cleaned the exhaust port, it's probably due by now. Use a thin piece of wood or other object that won't scratch the metal to get the carbon buildup out of the port on the engine. See if that does the trick.
