I am a novice at this sort of thing but I'm trying to learn.  Problem is, my sources conflict.  What to do ?  I have two old machinists, both claiming to know what's best, one is 92 and sharp as a tack and the other 73.  I have a Holley 2 barrel that appears to need a good cleaning.  One says two oil the springs (external) because my throttle isn't returning as far as it is supposed to and this carb looks like it's been around a while.  Then other say NEVER oil springs on a carb, they will gather dust with oil and won't function properly after.  Which one is right ?  I am getting a new tri-power in a few weeks I think but I still want to know, which guy is right ?  Is it wrong to oil the external springs on a carb ?
