Rotarians,
Thanks for all your replies of a
couple of weeks ago. Tried most of what you all suggested and still
couldn't get it to start. It just kept flooding. I kept pulling the
plugs, blowing them out and trying to start it. Frustrating is not the
word for it. I did notice that if I turned my controller to number 8 and
hit the primer switch, all the plugs would fire, the prop would move a few
degrees and then my plugs would no longer be wet, and when I charged the battery
up, I could try again. After much trying, I called Tracy and sent it in to
him. It turns out that there was a missing capacitor from the factory that
enables the unit to use the 2 wire Renesis CAS. It ran fine during Tracy's
initial test, but he used the 3 wire 13b CAS. He soldered on the sensor,
Now tests them all with both CASs and sent it back. Tracy, thanks for the
troubleshooting and the quick turn around. I learned way more
about this engine than I wanted to know, (but it is probably a good thing
in the long run).
I put it back in the plane and tried to fire
it up. Could tell that it was trying and not flooding as bad. Finally
after a couple of battery recharges, with the mixture very lean
and no prime and the throttle full open, it started, with
difficulty, revved high before I pulled back the throttle and it
died. It shook a lot! Maybe more than a Lyc. With a
lot of trouble, I was able to get this to happen 3 times then called it a
day with a partial success. Came back the next day, to similar
results. After about the third time, in 3 hours, I thought
to check to see how hot the exhaust was. #1 was warm, but #2 rotor
was stone cold. Figured I was only starting on one rotor. One
by one, switched out the plugs, coils, injectors to no avail. I
was just about to pack up and it occurred to me that some one (Lynn?) said
some thing about it not being able to start if there is no compression
and the way to get some, (if the seals are sticking) is to add a little oil
through the spark plug holes. I did this to rotor #2, Started it
lean with difficulty. It started the same way and then suddenly took off
to high revs and smoothed way out. Smooth is nice! I backed off
the throttle and no matter what I did it died again. It ran
for perhaps 15 seconds. Both exhausts warm! I quit for the day. I went out for short time today, got it
to start like this again, with oil, but ran the battery down. Packed it
away and went flying to get current again.
So I ask for your thoughts
again. I seems that the seals are not sealing on #2. How do I
get them to loosen up? I assume they are just stuck from sitting for
a little over 3 years. I did turn the engine over a couple of turns
every couple of months and a lot more the last few months. I
suppose that #2 could have gotten something in it during the
building process ever though I was careful, but I am hoping that the
seals are just sticking and there is a way to un-stick them. I
thought that just running the engine would do it, but no
joy. Your suggestions please. I will continue
plodding along.
Envious of you who just turned it over and it
ran.
