Okay, as with all bikers, comes bikers' wives. And mine is not too happy that I bought a drum, yes, a 54L drum of industrial grade engine cleaner. I've got to get rid of it before the lawyer can finalise the divorce and division of assets. I use this to rebuild engines, look at that pics, that's a 1983 Honda C70 engine. Spray it on unmixed, let it soak for about half an hour, that "encourage" the gunk to leave with the help of a paint brush. $5.00 for a litre of this stuff. Check out the pictures for details. Collect in the east.
