>Might try turning the pilot or going up to 120 mains.
Yeah, it'd probly do to open the pilot srews a bit at a time & see what happens.
They're probly sitting at about 1 1/2 if they haven't been adjusted previously.
I think you probably have 120s already (unless UK is different), but wouldn't doubt if they could be bumped a bit.
Also consider balancing - Particularly if different symptoms persist side to side.
