With mine, at least, the noise is there-a small knock-but what I am trying
to rid myself of is the backfire that prevents me from driving it.  I paid
very little so i reaslly don't care if it is just worn out and dies, but I
want to be able to drive it until it does.  Thus, the knock doesn't deter
me, but the inability to get up to speed does.  Any chance that the knock is
unrelated to the sticky valve?  My old Scout had sticky lifters, but no
knock.
