That may well sort out the occasionally sticky piston. If not, would it be worth re-centring the needle?

As far as the slightly raised piston is concerned, I now wonder whether the choke cable needs adjusting on the rear carb. If the choke cable position means that the fast idle is still slightly 'in play' would that not have the effect of the piston raised higher and thus sitting differently from the other carb?
Disconnect the choke cables and check. Easy. Check needle re-centering.Easy make sure that you disconnect the carb linkage before tuning so that they are both working independently when yo make adjustments.
