Before there was all these bogus tigerwizz products, there was Mystery Oil. The 'gandaddy' to all that stuff. See the part about 'mineral spirits'? You should figure it out from there. The first cheap trick you did when the engine ran rough, was pour a qt. of Mystery Oil down the carburetor while the engine is running at a high RPM. They knew they were cleaning out something. Just what they cleaned out didn't matter. It fixed it. Combining mineral spirits with oil was "voo-doo" science back then.

Yup. We had a lot of voo-doo science back then...
