Partzilla mini-rant

3 parts isopropyl alcohol to 1 part oil. Soak as needed. Don't think you should boil this concoction. I haven't or read about doing it. Could be wrong of course.

Boiling in water is a separate method for immediate softening and installation. It is temporary. I have done this as well, or at least VERY hot water soak, and then used a heat gun to help maintain the temp right up to carb install.

 

Gotcha. The boiling was the oil and water, no alcohol. I've seen this verbatim elsewhere, but this is the instruction I planned to follow.

Think alcohol is better? I don't know the chemistry of it.

 

I do not have personal comparison experience to relate. I would expect the alcohol thins the oil without wanting to separate so the portion of oil is appropriate for the job and there is enough volume to submerse the piece(s). Real Wintergreen Oil is very concentrated/strong and expensive. Also, the last time I checked, oil and water still did not mix.

I just know that all of the posts of vintage guys that use the oil do the alcohol ratio mix and soak. And I have done it and it is borderline witchcraft.

Unrelated story... right after doing it the first time, our yard was overrun with ravens, crows, black cats and snakes. Dismissed as... coincidence.
