Hey guys, thought I'd post an update. I ended up hosing it down with the pressure washer, came up nice.
Drained the old oil and filled with some new stuff. Put new fuel in, primed and it fired up. Mowed the lawn, seemed to do an alright job, though adjusting the base to level 3 or lower (shorter grass cutting) seems to make the mower cut out.. maybe because its 99cc ?
Either way, seems to run alright, even though I didnt take apart and clean the carb.. dont think it needed it.
