so, maybe I'm wrong here, but to me a huge backfire on starting fluid
means a) too much fluid and b) the timing is -way- off, not a little
bit.    ether shouldn't backfire because the intake valves should be
closed when it triggers.   I'd double check that.   static time it to
whatever is appropriate for your dist -
http://www.oldvolkshome.com/ignition.htm - that should be close enough
to prevent any kind of backfire, and good enough to get it running.
7.5 BTDC I'm guessing.   Or just set it to zero to be safe, it'll just
make it idle bad.  (though I forget what that might do to FI - but I
think it should be tolerable).

unless you've got one of those big lumpy cams with a lot of intake
overlap....but I can't think off the top of my head of any factory
cams that should have that kind of overlap with the intakes open.....
(or very high compression, enough to compression ignite the ether)


personally, though, I've been using brake parts cleaner (the
non-toluene and non-chlorine stuff - co2, heptane, and alcohol) as a
starting fluid when needed, much less flash crazy and does a fine job
(unless you -need- to compression fire).   (my old IH doesn't get
started much, and when it does, it takes a lot of cranking to fill the
bowl....)
