adjusting holley floats on shaky engine?

if you have the float bowl off turn it upside down take one of the screws that holds the bowl on and you should be able to run the screw under the float. it should just drag it.get it like that and its close enough to race......Artie

I heard the same thing with a pencil. Electrics are nice like that. Can you run it at a fast idle to mellow out the vibrations. Ilove the fact that the gas spews out the adjuster when you crack the lock screw...
