The antifreeze treatment works great for glow engines, but I have to admit I've never gotten around to using it on a gasser. I usually just use that degreaser from Costco that I mentioned, and carb cleaner spray for the internals when I take them apart. Let me know how the antifreeze treatment works on a gasoline engine. I would like to know, and particularly would be curious about how it does on dissolving carbon.

Also on the subject of cleaning, do NOT use the carb cleaner/choke cleaner sprays on Zama carb internals. It ruins the various check valves in a Zama carb in microseconds. (Don't ask me how I know....) I've never had a problem cleaning Walbro carbs with carb spray, but I just switched to blowing out all the passages and verifying they flow with WD-40 only just to be safe.

Soap box time.... Man, it just irritates the ***** out of me the way they sell antifreeze all diluted nowadays. When I was a working mechanic, it was often difficult to drain enough out of a car cooling system to get enough pure antifreeze back into it for the proper mixture without getting the car up in the air and fighting (many times with great difficulty), to get the block plugs out to drain the engine completely. With this diluted crap they sell now, it would be absolutely necessary to drain the entire engine block, and in most cars add two gallons instead of one to get the proper mixture and protection. Big rip off!!
