Chris;
Great; sounds like things are going
well.
First of all, with all the talk about
injector sizing, I now have all my injectors matched in size per the
recommended size of the Mistral test pilot out of FL. They seem to be
working swell. However, as has been noted here, they are waaaaay larger
than the conventional wisdom found here at 62.7 lbs/hr / 646cc/min.
Since from what I have read, Mistral has done tons of R&D, what do ya'll
feel is the purpose of these large injectors?
Hard to know what
their reasons were; but I wouldn’t be concerned. I’m sure they use them
on the turbo version; and want run on just two. My injectors are 560
cc/min, so not that much less. The only down side I can think of with
the higher flow capability is getting smooth running at idle; so if that’s not
an issue…. . .
Second, after I have moved the
throttle to WOT, when I move it back to idle, the idle RPM is much higher than
it was before. I may have a smooth idle around 1700 to 1800 rpm, but
when I go WOT and then bring it back to idle, the RPM is now around 2200 or
so. If I "pump" the throttle a couple of times, it tends to settle
back down to the 1700 range....if I mess with the mixture, I can get
smooth idle around 1400 to 1500.
Sounds like maybe a
problem with the throttle linkage. Can you check and see that when you
pull it back the throttle plates are fully closed? Is there any adjustable
idle-air bypass on your system? And you might want to check your idle
stop – it should idle down to about 1000 so when you pull the power on final
the prop will help you slow down.
The last two standard oil filters I
have installed are leaking from the seal. I checked the mounting surface
and do not "see" any flaws, however, I am leaking quite a bit of expensive
synthetic oil (following the first six hours on dino oil) from this
location. I thought that perhaps I had tightened it by hand too much and
it warped the sealing gasket. However, it still leaks following a less
tight fit. I have never had a problem with this kind of filter
before. Please correct me if I am missing something. You lube the
gasket with oil when you install and only hand tighten it. Should not be
a problem. Any thoughts? I have had this with the last two
filters. The current one being a K&N...the previous an
STP.
First thing to try
is tighten it further. I don’t know your filter placement, but you’re
probably seeing 80-90 psi pressure there. Get a filter wrench on it and
give it maybe ½ turn past hand tight. I won’t hurt the
seal.
What’s next? Is
that bird about ready to fly?
