| Subject: | RAM Heads Installed and Running |
--> Stratus-List message posted by: "Hinde, Frank George (Corvallis)" <frank.hinde@hp.com>
Did you increase the size of the needle jets?...Mine had to go up a few
sizes. You can't simply change the main jet size and assume it will fix
the cruise mixture, the Bings simply don't work that way.
Tie the plane to a post and run it to cruise fower for a minute and cut
the ignition without changine the throttle...The check the plug colour.
You may be running very weak otherwise.

where exactly are your egt's? after the elbow on the stock stratus
exhaust? how many inches from head or elbow?
thanks and congrats,

Amen to that!
Like Larry, I also had a in-flight ign failure, but mine was on the primary
ign and not the backup as Larry's was (nice job Larry being able to handle
that on your first flight!).
NOW if I happened to have Larry's backup ign installed in my plane, and I
was running BOTH ign's continuously and my primary ign then failed I would
have fallen form the sky like a brick, all the while thinking my back up ign
was going to save my butt.
Yes people do run both ign's and get way with it, but coming from a guy
that's been there & done that ..... no thanks. I do my ground check, then
take off and shut down #2 and have it there if needed. It's really no big
deal to switch over to the other ign if one fails. Heck I was at less than
900 feet AGL when my went out. It's amazing how fast you can react once that
large fan stops turning to keep you cool.
On a side note, this past weekend I added carb overflow tubes to my Bing
carbs to route any fuel overflow harmlessly AWAY from my exhaust system.
Having heard the stories about nasty things happening if you simply lengthen
the existing tubes I wisely (or so I thought) made my existing tubes dump
into approx 1/2" dia tubes. I was thinking this would not cause a problem
with the carb pressures as I had lots of clearance between the two tubes,
and they were only slid together by 1/2" ....... WRONG!
All was normal on takeoff until I reached the end of 07, then the engine
started running VERY rough. I then slowly turned and knowing I would never
make it back to 07, landed on 18 while loosing more rpm the entire way. I
think I would rather have my ign fail in flight & switch over to my back up
than do that over again, as it was NOT a fun flight. After landing I pulled
the Bing overflows out of my newly installed larger dia over flow tubes,
then changed my underwear and went for another flight. All went well that
time. So how are others handling this issue, must one go to 1 inch dia tubes
to prevent the pressure change issue with these tubes?
Thanks for listening,

Yes but can you do it at VX 30 feet off the deck trying to get over a
very large tree?
What if your "changeover" switch should fail?...You then lose both
systems?
Its your airplane and you need to be comfortable but there is no way
(and I didn't) I would design my system to rely on any shared components
which represent a single point of failure.
I run both systems from an individual single on/off switch (main ign is
from the key switch) and you can check your system on the ground because
when you turn on the second ignition the RPM's pick up unmistakenly...I
wired both mine to a lead going to the tach so you can also read the
RPM's from both systems.....Becareful not to use a chagover swith here
either because if the lead grounds out both systems will die.
Both systems are fed from two independent batteries also. It would take
a mechanical failure (not the alternator because the two battery systems
are isolated) to stop my engine as both systems run all the time.

Frank and Kelly,
You both put forward a very compelling argument for splitting my system a
little further in
than the A-B switch. It is now fed as extension to the ignition switch, so
it'd
be foolish not to take that separation right out to the main and essential
buses.
Can't say I've been comfortable since the B-ignition dropped out on the last
flight.
I'm right in the midst of re-wiring connectors so that I can use Paul
Messingers Dual Dizzy
system with paired XL600 pickups, TP45 modules, etc.
Good timing (no pun intended;-)
Larry

Thanks for the tip Gary, I've never seen or heard of these. Got any info on
were I can pick up a set?
I've got a Bing manual but don't recall seeing these items.
