What Gareth is saying is that if a "tuner" has crammed a knibbsy "super monster", or ox "magnum jumbo stopper".....into the poor thing, dont strip it anywhere where you have just done the ceiling
Seriously though.....dont be put off mate, just having a giggle while waiting for the rain to stop.......even with a fair bit of preload from a performance spring, just take it easy, follow the normal precautions, and it will be fine
