Carb air piston resistance

Hello carb gurus:

Having rebuilt the carbs on my '69 TR6 I've noticed that the air piston in 
one carb (front) operates more freely than in the other one.  This is with 
simply a "raise the piston by hand" test and letting it return under it's 
own resistance.  Carbs still off the car, no damper oil installed yet.  The 
front piston more or less just flops back into position.  The rear piston 
returns with a little resistance.  (Not much but a definite difference)  
Which is more desirable and is the process adjustable.  (New springs?)  I 
practiced EXTREME cleanliness on reassembly so I'm not worried about dirt in 
the newly finished carbs.


My project grew from carb rebuilding to blasing the manifolds, removing and 
refurbishing the radiator, and replacement of assorted fittings and hoses, 
etc. and so on.  I want to get everything back together this week but am a 
little concerned over the difference in piston resistance.  Can anyone help? 
  Rex, Dick, are you out there?

Thanks and best regards,
