Kelly, can you tell me if the Aztec or Comanche came with Slick impulse mags?
I think the problem might be that the D4A5 technically did not come with impulse
mags. For us, Lycoming offered them as an 'upgrade', but still called the
engine a D4A5.

Jason, I can tell you that my C4B5 came off an Aztec and it had the Slick impulse
mags on it.

David, I glanced at Lycoming SSP-401 which gives the lineage of the engines. Here
is how the IO-540-C4B5 plays out....
IO-540-C4B5 - Same as C1B5 but with more effective counter weights for use with
Hartzell compact propeller
IO-540-C1B5 - Same as O-540-A1D5 but with Bendix fuel injector
O-540-A1D5 - Same as A1B5 except for Retard Breaker Magnetos
O-540-A1B5 - Same as A1A5 except for short propeller governor studs and two impulse
Magnetos
O-540-A1A5 - Same as A1A but one fifth and one sixth order counterweights
O-540-A1A - Two sixth order counterweights
So from the looks of it your engine should have had retard breakers tracing back
to the -A1D5 and a fifth order counterweight traced back to the A1A5...
Is there a more efficient way to find out exactly what accessories were on which
engines?

I don't know, Jason. I googled the sb and found this 1999 bulletin from Piper.
Clear from this that the C4B5 on the Aztec was not on the list at that time.

The c4b5 does not have the option of impulse coupling. Look up slick magneto and
engine and I believe you will not find that option.
The Aztec engine I first used did not have impulse coupling 1980.
When we were thinking of switching from slick start to impulse we did a intense
search and that is what we found out. Impulse will work but joe at champion really
advises against it.
My two cents
Patrick Thyssen
Ps another note we just found was the k&n filter shrinks over time and needs to
be replaced its not a life time filter.

I found the same thing this year on the filter. Mine had shrunk
CONSIDERABLY.
I bought a replacement, but didn't replace it yet...first I had to
re-rivet in those
holder tabs that keep it from moving around. Or maybe I did replace it.
I can't remember right now. But, I know the new one will shrink too.

No Lycoming engine came with Slick mags until Continental bought Bendix
mags (long after both aircraft were out of production). It was a Textron
corporate decision to change to Slick mags for everything except those
for which there was not a Slick equivalent, like the dual headed single
mag engines.
So no table of differences between engines is going to tell you what
they are currently shipped with. However, ALL new and rebuilt/overhauled
engines from Lycoming will come with Slick mags with the above noted
exception. Changeover was more than 20 years ago.
Service bulletins and ADs are written to either be very specific about
what engines or airframes, OR to say they apply to all engines with this
specific appliance, batch of parts, etc. Almost all lists of parallel
valve O-540 and IO-540 engines suitable for the RV-10 are models with 5
as the last digit. Only a handful of those appear on this Service
Bulletin, so there is some characteristic about the specific engines
they aren't telling you.
I would suggest contacting both Vans and Lycoming to ask their tech
support as to whether the SB applies to the D4A5 engine or not, whether
installed in a Comanche or RV-10, and if so, why the Comanche as a
certified aircraft is not listed on the SB. No need to ask about the
C4B5 because it is an identical engine except for data plate and
governor redline setting.

I don't know why an Aztec couldn't have impulse coupled engine. There
are several versions of the engine that do have impulse coupling,
including the C4C5D
the D4A5, the D4B5, etc. Piper and other manufacturers went back and
forth between impulse coupling and retard breaker starting systems quite
a bit back in the sixties and 70s. Only the presence of a vibrator, the
wiring and ignition switch are different. The retard breaker has had
less ADs, both otherwise both are pretty equivalent for starting.

I had the same thing with my filter. Mine shrunk and also was cutting into
the fiberglass. I did replace
Mine at my annual. I prosealed A .03-.04 aluminum ring in the fiberglass
housing. It worked really good. Got the idea from someone else On VAF. My
filter was almost a 1/3 thru the fiberglass. Here is a PDF full scale of the
ring

All,
I posted a couple of notes on this awhile back. This is how I solved the
problem.
This is a mod to the air box I did on the RV-10, and just now back fitted
onto the RV-8A.
Over the years with the RV-8A I've had to repair the air box and replace the
filter. As you can see from the first photo, the bottom of the filter
deforms (curves in). This tends to shorten the filter such that it drops
out of the top and impairs the seal with the top plate. I also had to add
fiberglass to the bottom of the air box as the relative motion between the
bottom of the air filter the air box eroded away the fiberglass bottom.
The fix was to add a .032" aluminum plate to the bottom of the air box. The
plate eliminates the bottom erosion and the added brackets hold the filter
shape. A side benefit is that alternate air door now sandwiches the bottom
fiberglass between two piece of metal making a sturdier install. I also
took the step to add proseal between the aluminum plate and the air box
bottom.
And a note on using a larger K&N filter for the RV-10
I found that the Van's air box can be easily modified to handle the larger
K&N E-1000 filter. Photo attached. This air box is made for the James
Cowl.
