Sometimes in life you don't want a stiff one, and this is one of those times.
I have a very stiff fuel main fuel tap (reserve is fine). I've given it the WD40 treatment and that hasn't made much difference, which means I've now exceeded my engineering expertise.
It's a circular style tap which you pull out for ON and then turn to lock in place, perhaps it's just liable to be very stiff, and that's ok, however I wanted to check whether any of you chaps have the same issue with stiffies?
Welcome your thoughts, extra marks will be given for the highest number of double-entendre's in a reply.
Thanks!
