Not sure this coud be it.  I'm getting six solid ker-chunks as I pull the blade through one rotation.  Is that proof of compression?

Stuck apex or side seal?

Happens alot if a rotary sits for a while without a good prep of
getting-out-unburned-fuel and giving it some oil in the chanber.

I Hope that is not the problem.  Check the compression to see.

Today, I planned to crank her up a do the first taxi test.  It would not
start.  I pulled the plugs and cleaned them. I verified spark and timing
with a light.  The closest I could get to a start was a few backfires.  I'm
getting air, fuel and spark, and all in the same propotions as I was
getting 6mos ago.  The only thing I can think that might be amiss is that
the fuel is 6mos old.

I've heard that gas can go sour, but I've never really believed it.  Has
anyone else encountered a situation where the fuel is so old that the
engine won't light it?
