Whip the air filter housing off and look at the carburettor end too.

The springy bit you describe is the kickdown switch, as outlined here:
By you pressing it, you are just shortening the outer cable. Have a proper look at the inner cable at both ends. Even my brother could manage to do this even though he's a grade A technical numpty.
So it's a choice of:
a) inner cable not sliding smoothly in the outer
b) pedal pivot stiff/seized
c) return spring at carb end
d) carb linkage stiff/seized
Have another look and determine which it is.
