Wintergreen Oil???

Not sure, acetone completely dissolves some plastics, not sure what it will do to rubber parts but almost nothing is pure rubber anymore. Try it on some really old and really dead parts first?

All we can say for sure is that xylene and winter green oil works on carb air box boots. I did try it on the o-ring gasket that goes between the petcock and fuel tank and it worked there as well. You mileage may vary and use caution on other parts. I want to say again. After a couple of days of soaking the parts do swell to about twice their size. They are very soft and mushy feeling when you first take them out of the solution. Leave them on a paper towel or newspaper to air dry overnight. They will shrink back to their normal size and loose the mushiness and feel like new parts. I have used this solution on Suzuki and Kawasaki boots with good results. Keep the solution in a sealed glass container and so far after reviving 8 boots and after 4 or 5 months the solution is still good.

Any more that the above and you're on your own. My guess is that any solvent that doesn't leave a residue and is known to not eat rubber would probably work. Don't come complaining if your cocktail eats your boots. You are warned.

Oh forgot to mention that I had about a 6 inch piece of rock hard fuel line that I was going to throw away. I soaked it for a couple of days and it felt good. I did NOT re-install it on a bike. I'm using it on my aux fuel tank for carb sync etc. When I need a 1/4 to 5/16 fuel line. Aux tank has 1/4 inch line. Then I have a brass 1/4 to 5/16 fitting for bikes that require 5/16. So far after two carb syncs the fuel line is still good.
