Lubricating Throttle Shafts.

["Otis Davidson" <otisdavidson@xxxxxxxxxxx>]

Hi Gang,

I've seen a few carb postings here lately,one concerning worn throttle 
shafts. Usually there are brass bushings where the shaft,on which the 
"butterflies" mount,goes thru the carb body.

I feel that these bushings should be lubed a little with a decent spray-oil 
on a regular basis...or even more frequently if an owner likes using spray 
carb-cleaner on a regular basis. I use Valvoline Syn-Power in the Gold 
aerosol can...from Advance,Wal-mart,etc for lubeing the shafts.

This is the way I have seen it done by a mechanic I once knew: He'd rev the 
engine up,then aim whatever spray-oil at the throttle-shaft using that 
red-tube extension that sticks in the nozzle and SPRAY...then slam the choke 
shut with engine revved a bit,almost killing the engine.
The logic was that with the dramatically increased vacuum created by 
slamming the choke shut....that the oil got sucked in,properly lubeing the 
shafts.

Just my .02 cents.

'75 Imp 4dr <--with a Holley with alot of miles on it...and perfect,original 
shaft bushings.
'79 440 powered 35 ft RV <--same. They'll get lubed again this spring.
