Took an old plastic Poulan 2150. plugged muff and carb, poured a little bit of old gas into the engine well, sprayed with engine degreaser, let unit sit for 5-10 mins.
Then used my air compressor siphon pressure washer and sprayed hot soapy water over all of the unit, twice.
Then blew dried best I could.
Don't look brand new, but can disassemble on kitchen table now, wife shouldn't mind, no greasy grime.
Thanks,
