Bernie, for what its worth, on cold mornings my engine will sometimes kick
off on only one rotor for a few seconds.  You are right its rougher than
anything I would want to be in the air with for long.  Generally clears up
after a few seconds - no problems on warming mornings.  It does sound like
you could have an injector problem.  I had one that stuck open
intermittently and about drove me nuts over three months of trying to solve
identify the problem.

Boy, wish I could make a similar weight claim about my lead sled.  I came in
about 120 lbs over the Van's average for an Rv-6A - although I have seen
those that do weigh more than mine.  44 lbs of batteries probably
contributed to that a bit, heavier than necessary wiring, motor mount,
exhaust system, AN-16 hoses, etc, etc. it adds up quickly.

Hope you get the problem fixed soon.

Ed

injectors

> The good news. My total empty weight (including approximately 1 gal of gas
plus oil and coolant) is the same as Van's sample weight and balance number.
I believe that is the number of their 9A with a 160 HP lyc.  If that is the
case then my weight is exceptionally good  because the factory works hard to
keep their weight to a minimum. The painted weight is 1072 and the CG is
less than a ¼ inch aft of the sample.  With 60 gal of gas and my 155 lbs
fanny, the cg is still not too forward and I would probably always have some
luggage if I'm loaded with fuel to push it aft to a better location.

> The bad news is that the run today still ran on one rotor for
approximately 1.5 minutes. It is rough! When rotor 1 did fire up, I had to
shut the secondary switch off to keep it running. This means that the
injectors are running way too rich and it appears that rotor 1's primary is
probably the culprit. Will pull the injectors tomorrow and see if I can
determine anything, May just buy a new one and stick in that hole. The
airplane is getting a real shake test when it is running on one rotor. Would
be scary trying to stretch a glide by keeping one running! Don't think I
will wait next time if it is only running on one rotor.
