<VV> Decarbonizing

[paul beck]

I worked for a number of years at a Chevy dealer, parts and service. It was fairly common pactice to decarbonize when we would get complaints of severe spark knock. 
Sometimes  worked, sometimes it didn't . We would get the motor warmed up and then let the engine injest about 1/2 a quart or a little more of auto trans. fluid through the carb, slowly. Then pour the rest in quickly enough to stall the engine. Let it set for a couple of hours and then start it up. Strongly recommend this be done outside, with a good breeze. Mucho smoke, before and after. The trans. fluid really softens the carbon up and no damage.
That being said.....does anyone have a suggestion for mounting a different (disc brake upgrade) master cylinder. Is there something out there that can be cut off or oherwise modifed?
Thanks,
