Using Anti-freeze to Clean engines?
Tom,
If the reason that the carb is froze can be linked in any way to castor oil,, then I'm sure it would work, it has for me, you may have to simmer the carb as a whole unit first, in order to get it all dismantled, then simmer the parts again to get them clean,,, give it a shot, no harm can be done by trying,, just remember to remove the o-ring if you can,,,,,,
here's a pic of an OS 91 pumper that I recently did, note the muffler, before I simmered it, it had really bad castor burnt on brown stuff all over it,,,,,,
