| Subject: | Champion Slick Magneto Maintenance Kits - new to me |
I was in the process of buying a couple of rebuilt (not overhauled)
Slick Mags to replace my 800+ hour Mags. Aircraft Spruce carries them
(along with new and overhauled).
However, my last search in ACS turned up Champion Slick Magneto
Maintenance Kits as shown here:

The hadn't noticed this as an option before but looks very attractive.
I've already fooled around with mine to comply with an earlier Service
Directive and would love to do the work myself if I can bring the Mags
back up to the rebuilt standard.
Is anyone familiar with these kits? Do they contain what is needed to
bring used mags up to the rebuilt standard? All input welcome.

Personally, I don't like to take chances with mag problems. I've had 2
occurrences of near engine out experiences with mags because I didn't keep
a close check on mag condition. Now, I buy overhauled mags from a reputable
source and have a complete mag check at 500 hrs.

I have machined two excess static ports and a tail light adapter available
for anyone who needs them. These are machined parts that are commercially
available from Cleveland Tools - but the only payment I would need is for
shipping. Please let me know off line if you would like them.

| Subject: | Fuel pressure problems continuing |
Hi everyone.
My RV-10 has 9 hours of flight time so far with a factory new Lycoming IO-540 D4A5.
On the last flight I did a couple of weeks ago, I tried a full rich climb
to 10000', but ended up with my fuel pressure dropping down to around 11 psi
when I got to 8700', at which point I turned on the boost pump and got the pressure
back up to around 20 psi. Back down at a lower altitude, I tried turning
off the boost pump, and the engine pump maintained pressure at 22 psi. But
something was clearly not right, and since I was pretty much at the right time
to do an oil and oil filter change anyway, thought it was a good time to do
the equivalent of an "annual" to make sure everything was still looking good,
and try and sort out the problem.
Looking at my logs from past flights, typically my fuel pressure with the engine
pump has been about 20-23 psi at 6000', 21 gph (full rich). I have typically
seen higher pressures on the ground (27-29 psi) at lower RPMs and fuel flows.
My fuel system is pretty much stock Van's, except I have an Andair fuel selector
with an extension so it's lower in the tunnel, and I have gascolators in the
wing roots (here in Canada, we require them). The fuel pump, filter, and fuel
flow transducer (red cube) are all in the tunnel, as per plans.
I thought I'd start with looking at the gascolator screens, since they're the easiest
to get to, and being the first filters from the tanks to the engine, likely
to collect the most. And I thought I hit the jackpot - both screens had
some sort of lint buildup in them. I thought I'd kept the tanks clean while constructing,
but guess it wasn't as good as I thought. So I cleaned them up figuring
I found the problem (assuming that since they caught debris, likely there
wasn't anything blocking things further down the line), changed the oil and
filter, put things back together and figured I'd go flying.
But in doing my runup, after a few minutes when the engine was getting warm and
running at relatively low RPMs, I turned the boost pump on for a few seconds
and then back off. When I turned it off, I saw the pressure dropping slowly.
It got down to around 13 psi. I tried advancing the throttle a bit to see if
maybe the engine was running too slow to provide enough fuel pressure, and the
engine promptly died. No sputtering or anything - just quit, like I pulled
the mixture to ICO and that's what I wanted it to do. It's not done that before.
Obviously, at this point I wasn't going flying until I could figure out what was
wrong. I managed to restart the engine (after a bit of effort - the engine
had warmed up a bit, and I'm still sorting out the best way to do that). I couldn't
get it to die again in the runup, so I decided to do a few high speed taxis/aborted
takeoffs (fortunately, I'm at a quiet airport). Normally when I
take off, I use the boost pump - this time I purposely left it off to see how
the engine pump handled things on its own. I did three, and every time when I
brought the engine up to full power and started a takeoff roll, the fuel pressure
dropped significantly. Twice down to 12 or 13 psi. When I throttled back,
the pressure came back up again. And this was tested on both left and right
tanks - both behaved the same.
So back to the drawing board, assuming there is still a blockage or restriction
somewhere. I re-removed the gascolator screens again in case there was further
contamination, but they look clean.. as do the fuel strainers that go into
the tanks. Tomorrow, the plan is to get into the tunnel to check the fuel filter
there (not looking forward to that - I'm going to have to remove a bunch of
stuff to get into there, and had thought that since the gascolator screens had
caught debris, the one in the tunnel likely will be fine). Nevertheless, it
looks like I'm going to have to inspect the whole fuel system with a fine toothed
comb to try and find if there's a blockage or something. I don't think
there are any kinks in the lines - they were all bent with a tube bender and looked
OK when I installed them, but I'll be taking another close look of course.
While I have everything apart, if anyone has any ideas of what to check, I'd greatly
appreciate them - I want to make sure I'm as thorough as possible, and don't
want to close things up only to realize later I should have checked something
else out while I was in there.
The engine (and presumably fuel pump) were new from Lycoming, though they sat for
about 1.5 years with preservative oil. How likely is it that the fuel pump
itself might be the problem? The boost pump manages to bring my pressure back
up to where it's supposed to be, but considering its design is different, it
might be more tolerant to a fuel system's quirks.
Thanks for any help or advice!
Dan
