I'm in a dilemma should I purchase my 912S now even though I'm a long way
from finishing? The warranty would expire before I can get it in the air. I'm
not sure of the length of the Rotax warranty.

Rick and others,
I used ethanol gas for 12 years and still use it occasionally. I never saw anything
wrong with my carb parts or had a problem. If anything, ethanol will soak
up the moisture in the fuel. Here in Minnesota, this is all they sell and it's
7%. If there was a problem, there would be cars that wouldn't run here.

Noel,
I fly in Minnesota and your engine may have been flooded as it's easy to do in
the cold and when you're anxious to get it flying. This happened to me more than
once, but the last time it was not due to over-priming, it was stuck rings.
Turn your prop over and feel the compression on both cylinders. One may have
no compression and is a sign of stuck rings. A more accurate method would be to
use a cylinder compression gauge. If it has stuck rings on one cylinder, it
will not start. I spent a night on a frozen lake in March of '91 when my plane
would not start with stuck rings. It got to -5F but I was dressed for the cold.
Adventure at it's best.
By they way, I flew yesterday on the frozen lake and most of it was in ground effect,
one wingspan above the ice. I can go for miles on these lakes up here in
the north country. Fun at best.

Hello "Kolbers" !
I am a long time lurker on this list but very seldomly post ...
I live near Montreal, Canada and today i had an engine out
with my Twinstar Mark II due to what i think is carb. icing ...
The engine started to run roughly after a 1-2 min slow descent from ~ 1500
to 700 feet and would not go higher than about 4800 RPM and was
probably running on 1 carb. So i just cut power and landed ...
(No bad consequence as i was 700 ft above the St-Lawrence river
when the problem hapenned so it was a "no brainer" to land on the
(frozen) river ...)
After landing i saw that one of the carb spewed a lot of gaz from the
overflow
Now ... i have never been able to restart the engine (Rotax 503 Point
Ignition)
after ... checking the carbs bowl, needele jet and changing the plugs
... and as darkness was
coming in i had to leave the plane on a peer by the river :-( and a
friend picked me up ...
BTW the temp was -8C and the dew point -10 C ... (14 and 17 F)
and quite a lot of humidity in the air ... Perfect conditions for Carb
Icing ...
So i am wondering why this engine would not restart ... and trying to
elaborate a stategy
to get back tomorrow morning and fix the problem ...
I tought of getting a new set of plugs and try again and if no result i
thought of getting the carbs off
and bring them to warm so to melt the remaining ice ... If it remains
there ...
Any advice from you northern flyers ?
Nol

I found those pesky bottom wires were a pain untill I made new wires. I
permanently mounted the tangs to the bottom tail post and I now install the
wires with clevises on either side. Works a lot easier and the wires are
tighter than the average Kolb.

Kolbers,
I think Ralph is right on the mark. Aluminum & alcohol are not
chemically reactive, nor are there any parts in our fuel system that will
deteriorate in its presence. ...Richard Swiderski
Rick and others,
I used ethanol gas for 12 years and still use it occasionally. I never saw
anything wrong with my carb parts or had a problem. If anything, ethanol
will soak up the moisture in the fuel. Here in Minnesota, this is all they

Several things come to mind, Richard. You're right, I think, about alcohol
and aluminum not being reactive, but alcohol will certainly attack some
flavors of neoprene. (or similar artificial rubbers) In my work as a
commercial kitchen equipment/refrigeration tech, I've seen o-rings that
swell and crumble like stiff cheese after exposure. Also, while working as
a timber faller in the north Idaho mountains in the late '70's and early
'80's, we used a product called "Heet" in our chainsaws during sub-zero
operation. I don't know what was in it besides alcohol, but we were
strongly warned that it would damage the magnesium in the chainsaws. We ran
it anyway, and I, for one, didn't have problems with it, but
still...........?? Again, I don't know if that would translate across to
aluminum, but it IS food for thought. Lar.

I am not a chemist but I have read articals that begs to differ. Eaa mag had
a artical about the Air show group that is burning alcohol and talked about
reactive with alum, Alcohol is.

Hi Rick & All,
Good point about alcohol and carbs. Keeping the gas pure is always preferred.
We went through a big learning
curve in the midwest when they started putting ethanol in gas in the '70's (remember?),
and carbs with plastic or
nonmetallic floats would become porous, eventually having to be changed out for
'alcohol-friendly' ones.
I used to build blow-molding machines (making milk bottles primarily),
and one of the biggest we built was for
the Ranger pickup gas tank. Had to make a big shroud around the machine for nitrogen
gas to be injected after the tank
was 'blown' but still hot in the mold. The nitrogen had something to do with making
the tank non-porous. Plastic
doesn't have to be porous to make condensation and water, just changes in temp
and humidity.

Rick, Larry & All,
Detroit has already been through this issue. There were materials
used in the past that were not compatible with alcohol. Millions of cars are
using alcohol with no problems to the aluminum carbs or synthetic materials.
I have used it in my mikuni's carbs with no problems at all. Same with
SeaFoam, I've used in all my fuel along with Marvel Mystery Oil, hundreds of
hours with no problems. After I send this I will put some Aluminum foil in
isopropyl alcohol & let you know what happens after a few days.

Hi Richard: I really doubt if you'll see any reaction between the alcohol
and aluminum. Automotive products are well proven to resist it as well,
but.....seems to my little pea brain that I've read somewhere about some
aircraft components still being susceptible. Wouldn't put money against it,
but.........??

Hi Pat/All:
I don't have the article handy. If I can find it and if I can
successfully scan it, I'll post it on an index page for folks to take
a look at.
However, there is a much better article about the same flight in the
May, June, July, and August issues of EAA Experiementer Magazine. We
had that one up on the Kolb web site for some time, but was taken
down. Dana Labhart had the files. Possibly we could get it together
and get it uploaded on another index site, or possibly a real web
site.

I have purchased a Kolb firestar and it is in a lot of

bills of material I got from Kolb Aircraft. They say
they can not supply me with a set of drawings for
reassembly since this model was not part of the

I would be glad to pay for them.

What actually made the alum nodules the messed up the diapram on the pumper
carb was the water from the gasalchol. I was young and dumb at the time and
didn't relize you were not suppose to use gasalchol. The water saterated
gasalchol warm out of the ground put in a cold tank on a ultralight that
didn't fly very offen means water sitting in the carb.and corrision. I
always figured the alcohol helped with the corrision.

Hello Group ...
Some follow up on the engine problem i had yesterday.
First my Twinstar is back on her nest !!!
... and the cause of the failure was not carb. icing ...
(It sure started a nice thread on gas additives he he ...)
The problem was caused by one of the ignition point that somehow would
not open anymore ! ?
After seeing that the shaft that actuate the point was "dry" (no
lubrification left at all), our theory was that
the wear on the nylon cam changed the point setting ... although it
happened suddenly ... ?
After checking (again) the carb bowls, main jet and raising the needle
one step we finally realised that one cylinder
seemed not to "fire" ... we started to check the ignition (changed one
coil) and finally found the problem with
the point ... By chance a friend came to help so we could get to the
points using his "puller" tool ...
The engine started shorthly after readjusting the points ... and on it
2 cyls !
Took off for an uneventfull 1/2 hour flight back home.
Did someone ever has such a failure (a sudden change in the point setting) ?
I did not say in my last post but the engine had only about 50 hours
since it's last full rebuilt.
Thanks a lot for the help and i will follow the thread on isopopyl and
additive and try to make up my mind
wheter i will use it or not ...
Good and safe flying all !

Kolbers,
The following article gives a good explanation of how to use alcohol in an
internal combustion engine, and the effects of different types of alcohol on
carburetor and fuel system components.

Several years ago I replaced the points on my 532 with a set from Airstar
Discount Sales which developed major wear in about 12 hours. The mag end
crank seal I got from them at the same time also failed in less than 20
hours. The points looked like standard Rotax parts, but I seriously doubt
they were.
Lots of junk out there, be careful who you buy from.

Now it sounds like we are talking about running straight alcohol as a fuel
substitute that's not what we are doing, we are just adding enough to prevent
fuel line freeze ups, adding 1.6 ounces per one gallon of fuel that's far from
running straight alcohol.
I have been using isopropyl in many engines and have never went out to start
a vehicle to realize the carb has vanished overnight from use of fuel
additive or even the slightest of any aluminum missing during normal preventive
maintenance

Hello Richard !
My friend who has rebuilt the engine said he bought the highest quality
part ...
But this doesn't mean he got what he paid for ...
My brother told me today how he found out a dealer was selling cheap parts
but packaged as the high quality (priced) part ...
It seems there's quite a bit of conterfeat(?) parts out there ... so i
fully agree
that one has to be carefull where he gets parts from ...
