For the price or new ones (top and bottom), I wouldn't even consider buying secondhand because you have no idea how old they are, how they've been looked after and if they have unseen cracks in them. Help the lower rubbers to seal to the cylinder head properly with a bit of Threebond (expensive but when you've used it once you'll never go back to ordinary gasket cement again). I treated LFB to a new set of rubbers after I got just a bit p!ssed off when she dropped to 2.5 cylinders in the Welsh mountains on the first day of a four day run. Unbelievable difference...
Despite what the can says, WD40 is no longer flammable like it used to be. (Thank the safety Nazis for that one.)
I use starter fluid although I've heard of others using propane or other flammable gasses.
You can also spray some water mist and if the RPMs go down then that indicates you've got an air leak.
