<VV> Die! Dieseling Corvair, Die!

[Frank DuVal]

I am also a big fan of the tiny stream of water through the carb to 
clean carbon from cylinders.

But, there is also a product that does similar cleaning, and it is 
designed for this, GM Top Engine Cleaner. AFAIK, it is only sold at GM 
dealers, but check around. Follow the directions on the can and it 
should work well.

I'll stick with water for the occasional knock exercism.
