[R-390] R-390/URR

[Cecil Acuff]

I agree with Bob getting between the split gears is the big issue.  I have 
shoved a knife blade down between them enough to allow a flush out with 
Gummout Carb cleaner.  Be careful with that stuff though...it's potent.

I've had good luck also with plain ole mineral spirits in a spray bottle and 
a tooth brush.  Leaves behind an oily film which ain't all bad!
