REFLECTOR: Fuel injection throttle body

[mb]

Actually, the servo is a very sensitive instrument.  If has no fuel in it, 
like it just came back from overhaul, NEVER operate the throttle lever.  If 
it is dry, according to my A&P/IA, the insides will score and fuel metering 
will suffer. Moving the levers before fuel has flowed into it is a big 
NO-NO.
I have no idea on how to tell if it "needs" a OH. But if has been sitting 
around a while, or has been stored uncovered, or looks dirty inside, I would 
spend the money to have it done.
