  I tried expanding the O-ring a bit by putting several layers
of teflon tape in the O-ring channel to go under and expand the
O-ring a bit.  It seemed to help and the fit was firmer.  When I
added some butane and lit it up, the engine burner worked ok but
there was still a little bit of flameup around the valve.  It might
have been worse if it was a complete fill-up.

  Now, I'm out of butane.  That will slow me down a bit which often
times is a good thing.
