If the finish is damage sensative to carb cleaner or other sprays, you can use a more risky procedure with propane from a cutting / brazing torch - or a BBQ Lighter (not lit of course) - same results but with greater risks from spark......
Let us know what you discover....
Thanks Brian for the tip that the supercharger want engauge in park while running up the RPM's. Squirrel Crusher
