Got a big riding mower with the engine in a crowded, tight compartment.
The engine has gotten very oily and greasy due to some oil blowing out the
breather. Problem is now fixed.
How do I clean the engine? My first inclination is simply to spritz it
down good with strong liquid detergent, let it soak awhile, and then flush
off with water.
That should get it cleaned up, but am I going to ruin anything by doing

Can't say mine have ever gotten that bad but a used Wheelhorse with a 20hp
Onan I bought last year was pretty dirty and clogged with clippings. I just
used a putty knife and toothbrushes, and shop vac (sucking and blowing).
I clean all my engines; mower, tractor, car, truck, etc., with a cheap
electric power washer: I spray full strength Simple Green over the
whole thing, a couple of times over heavy crud, wait a few minutes, then
spray away. Sometimes I even spray it again for stuff I missed, or parts
that didn't come clean enough. Cover any exposed air intakes.
