Haha, you wil never get it CLEAN like that. Here is how I cleaned mine last week.
Bought of bottle of commercial strength liquid degreaser at AutoZone. It is like a 1 gallong jug, its a purple fluid. I hooked up my craftsman pressure washer gun to my air compressor. The gun hooks up to my hose, the air compressor, and the bottle of degreaser.
I just blasted the whole engine, everything in there. I looked out for the air box and fuse box, but didnt avoid them. Damn, SOOO clean now. EVERYTHING is clean, not just the top of the engine.
A coward dies a thousand deaths.
