Steve,

It might be useful to reset the EC2 timing mode 8 setting to the default se=
tting. My EC2's do not produce consistent or strong sparks at RPM's  less t=
han 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 consist=
ent low RPM sparks are obtained at the most retarded mode 8 setting, but th=
e EC2 must be receiving CAS signals (engine running) in order to make this =
change.

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.

Regards,
