I got the Yamaha carb cleaner, but the instructions don't cover dipping. Do you use this stuff straight-up, or cut/mix it with something (I'm guessing straight)? Two floats (550-K1; 022A's) are stuck and there's other gunk, so I'm thinking of dumping the whole thing in as-is to loosen it up, then dissassembling everything and re-dunking them more properly. I recall this can be done with the Yammy cleaner without trashing the floats, etc., but how long should they dunk: when complete & then dissassembled? I'm looking at a total rebuild, but think re-using everything but o-rings and gaskets would be nice. Thanks.
