(1) Gas that has been sitting around for awhile
will tend to have a lower effective octane than its nominal rating. >>
Hi all,
regarding `gas sitting around`. I found this year after a lot of prop
swinging that it actually loses its explosive capacity completely and the
engine will not start.
After trying all remedies to start up the 503 after the winter lay up. I
drained the tank and replaced the fuel. Fired at first pull. A friend in the
oil industry told me `it doesn`t keep like it used to`.
Cheers
Pat

-----------------------
it seems to me that the reg is they have to post alcohol at 10% and above.
dont take this as 100% garranteed......but that is what i remember.
it is easy to test for..... put water in a jar and mark the level.....
add some gas, an equal amount to the water, then put the lid on and shake.
let it settle.... if the water level has increased that will be the amount
of alcohol in the gas.

Duane et al:
I have found that when balancing the 912 carbs, being able to operate the
vacuum gauges with the engine running is very useful. This can be done in
my Mrk III by removing the between-the-wings gap seal, hooking up the
gauges so that they hang down partially into the cockpit, then starting the
engine (plane tied down of course) and carefully standing up, so that one
foot is on each seat and your head pokes up through the center section.
From there, you can make carb adjustments with the engine running and get
simultaneous feedback from both the gauges and the engine sounds. A
careful tap of the foot can adjust the throttle. Takes a little care, and
getting your head up through the gap seal is a bit awkward, but once there,
this method has worked well for me. So far, no door replacements : )
On a different thread, there has been discussion of methods to extend the
instrument panel. Thats fine, but for me the only instrument I want to be
able to reach is my EIS. An alternative to extending the panel is to
install remote buttons for the EIS, which could be placed right below the
seat. I believe Grand Rapids Technologies can set you up with this system.
I personally have not yet done this, but I believe there are others that
have - perhaps someone could report back with a price and their level of
satisfaction

It's from this group that I first learned about the remote button leads
for
the EIS, even though I'm a dealer for them. I've started equipping Titans
with them, since they have a similarly small panel that's difficult to
reach. There is no cost from GRT when adding this option to their EIS.
I wired 2 of the 3 buttons up to a G-107 stick grip, which has a total
of 5
function buttons. See
http://www.ultrafunairsports.com/TitanSS/panelfinished.jpg for a picture. I
used the top 2 momentary buttons on the grip for the 2 left button
functionss on the EIS. This gives me the ability to acknowledge the big red
light if I need to, and cycle back and forth among the pages.
I used the other 4 buttons for flaps and in-flight prop, along with the
forward button for PTT. If you didn't have a use for those 4 buttons, a
G-105 grip is the same, but doesn't have the two top bottons. You could
wire 3 of the 4 buttons for full functionality of the EIS.
Hope that helps,

If what your doing is working, why change. According to the manufacturer
operating manual 87 octane is fine. Running the higher octane level
increases the chance of your getting alcohol blended in as octane
booster. I run 87 unless I have reason to belive the fuel may set for a
while then I buy the 91/93 grade. I also use stabilizer which does make a
difference if it sits in the can or the tank a while before the next flight.

| Subject: | Rotax 912 startup procedure |
--> Kolb-List message posted by: "Jon Croke" <jon@joncroke.com>
Just got back from one of those Rotax 4 stroke seminars (3 day) held at LEAF in
Wisconsin.
Wanted to share a tip I never heard before for ALL 912S owners. This is from Eric
Tucker, the Kodiak distributor rep:
IF you are still fighting violent engine shake at startup (important: assuming
you have the HD starter and slipper clutch already), then try the following:
TURN OFF one of your Mag circuits instead of turning them both on like you usually
do. Once the engine starts, THEN turn it on!
This technique has apprarently been met with great success in reducing the shakes
at startup. The theory is that a single mag retards the timing by just a little.
When shutting down, you can reverse the procudeure (shut off one mag), then the
the other. (if you are having shakes at shutdown) (I'm not referring to the shakes
you might get from experiencing one of my STOL 'in the tree' landings!)
This is not an official Rotax procedure, just a technique that has worked well
in the field. F W I W
Another 'news to me' thing is that there is a brand new carb socket introduced
by Rotax a month or two ago... harder rubber composition, NOT a mandatory replacement,
tho.

Jerb,
I have been using Opti II two cycle engine oil. It comes with a stabilizer added.

Doug,
FYI, The increase is 4% for Rotax only. The actual price is increasing a total
of between 15-20% (including the 4%) due to the Euro/US dollar ratio. That
will add a good $2500 to the cost of a 912S. Yikes! Jim

I have a single carb 503. Last spring I fogged the engine, drained all the
gas and put the plane in storage for the summer. This fall I can't get the
engine to run worth a darn.
Last fall it was running sweet. Now I can't get more than 4000 rpm and the
engine is running rough. Last fall I was getting 6200 static at full
throttle.
I have tried everytning I know but can't get it to run right.
Any one care to make a suggestion.

I assume that when you say "all the gas" you meant the tanks and the
carb. bowl?? Have you tried new spark plugs? Does is run smooth at low
rpm's and just not able to develope full power, or is it running rough?

Is there anyone on the list that is still running a Cuyuna in anything? If so,
I would like to converse with you. Nothing in particular, I'm just tired of
reading about Rotaxes.
Maybe we could start a Cuyuna list.

gave any particular trouble that I can recollect... reliable...easy to
keep.... did want to run rabbits occasionally, though... had to work it in
right close with a whistle...
Whut sort of list did you have in mind...?

For not much more than the price increase of a 912 you could put a VW on
your Kolb. I have 180 hours of test time and experience that I'm happy to
share with anyone else that wants to fly a VW on a Kolb.
I still have a adapter mount, exhaust pipes, and Diehl accessory case that
could be used to try a VW on your airplane. Make me a offer on the package
and/or suggest how I might share these parts with the Kolb group.
I'm app. two weeks away from having my VW powered Kolb flying again. I can't
believe the number of changes caused by lowering the engine just 5 inches.
Hopefully when I'm ready to fly the all the standing water will be frozen
but not covered by a foot of snow here in Michigan. It's also a race to get
it done before I head to Florida for the winter. I also want to beat Vamoose
into the air.

Ah, Man, I think you've beat Vamoose into the air 2 or 3 times awready. Got
weathered out last weekend, (in Palm Springs ! ! !) and went fishing in Baja
the weekend before. Looks good for this weekend to get the engine running
again, and tidy things up a bit for the inspector.
