Cheers Christ.......just before I read your post I did exactly what you just posted. I used the small red straw on the Wd40 pulled up the latch and started spraying.......this enabled me to pull up and twist off the small latch and then I sprayed a shitload of wd40 down the hole........it's working now so the big test will be what happens when it gets a little warmer. But so far it's done the trick, cheers guys.
