RE: how to clean stuff
I use to do the dish washer trick, boy did the wife get pissed when she seen it in there. Now I just remove engine pipe and radio tray. Hang it from a tree and hit it with simple green, let it sit for 10 min then hit it with a garden hose, air dry rather a compressor or wind then wd 40 it down.
The pipe/engine is done with nitro cleaner. Cap off the carb and exhaust port and give it a few shots and its done.
