But does the alloy piston have a steel weight on top? If it doesn't, it might be you have the wrong piston for the carb. I've 6 Morris 8 type 1 1/8 SUs and have had them fitted to cars for many years. None have a spring, all have weighted bronze or alloy/steel pistons.
The damper makes it difficult to raise the piston because that's its job. The piston shouldn't be easy to lift as that means it will rise too quickly under acceleration leading to the symptoms you describe.
