Is it possible that older IPs are worn enough that they are beyond the range of the ALDA adjustment?

Could definitely be the case that a 20 year old IP is providing less fuel than a brand new one. Accordingly, you'll definitely need an ALDA and the older engine can easily be run without one.
Removing it gives no control over the rack other than your right foot. You get maximum fuel when you mash the pedal, whether the engine can use the fuel, or not.
