Steve,

It might be useful to reset the EC2 timing mode 8 setting to the default setting. My EC2's do not produce consistent or strong sparks at RPM's  less than about 1200 if the EC2 timing is advanced using mode 8.  The greater the advance, the weaker the spark.  Occasionally there will be a strong spark, but the timing on these is very retarded.  With my EC2's, the most consistent low RPM sparks are obtained at the most retarded mode 8 setting, but the EC2 must be receiving CAS signals (engine running) in order to make this change.

Subject: [FlyRotary] No start after engine replacement

I replaced my original engine with another newly rebuilt block, and also
added the EM-3 to the installation. The old engine was hard to start,
and was also making a ticking noise when it did start, which didn't used
to be there.

After several failed attempts, and double checking the connections, I
had a neighbor help me do some testing.  While the ignition test runs
fine, when checking one of the plugs, it sparks when I initially crank
the engine, and then stops.  Once in a while there will be another
spark, but not very often.

I reinstalled the original CAS and have the same issue.  I have double
checked the CAS connections and checked them with an ohm meter to the
connector on the EC-2 also. Everything seems to check out, yet I get
only that initial spark. I have replaced the spark plugs with new ones,
and whenever I pull one to check it, is is wet with fuel, which is no
surprise.

I am wondering if anyone has seen this type of problem, or if you have
any suggestions.
