I picked up a Toro 824 Powershift snowthrower today that was on c.l. and can't quite identify the engine make.

Ordinarily these would be Tecumseh Snow Kings, or Briggs Intek Snow on some later models. It's an 'L' head with the spark plug angled toward the front to accomadate the top mounted steel fuel tank, like a Honda. The tinware is all black, with metric fasteners and dipstick markings are in cc's and ml. The muffler is completetly surrounded in a shield. I entered the model 38250 and serno 8000309 in Toro's site and came up with a model 421 so that didn't work. Any ideas?
