If the plugs are black you must be really rich.
With at stock exhaust ( skystar chopped one - robs about 5 to 7 HP from you over
stock Rotax exhaust, but you cannot fit a stock elbow inside your cowl) you
should be ok at the 3 rd notch on clips with stock jets and needles ( 11G2) You
are in Michigan and altitude should be ok with this. Once the temps get down
below 40 to 50 F all the time you could go to the 4th notch (bottom on the
needles)
You never said what static RPM you are getting? Prop pitch can make a huge differance.
Also Make sure your needle/clip have the O ring on it and put in in the slider
first then the plastic piece or you will be very rich.

IVO does not like to mix 3 bladed props with 3 to 1 gearbox due to harmonic issues.
I run 3 blade warp on my 3 to 1 box with no issues. I have run other
3 blades props as well with no issues yet. GSC 68: a good working prop.
IVO medium you will only be able to run 2 blades but they work good and sound good.
Call Bob Robertson today 1-866-418-4164 toll free. HE had a demo 72 " 2 blade
IVO Medium there. Not sure if he still has but it might be priced right if
he still does.
I have used about 10 different props on the same engine combo that you have and
they all have their attribute and all perform with a few % of each other.
I have a 70 or 72 " in flight adjustable GSC hub with WARP blades with SS leading
edges here . 1400$ ( brand new is well over 2k$ ) this one has new blades.

| Subject: | Gas Tanks (One more time...) |
I had a thought about the ethanol/gas tank issue.
We all can agree that ethanol and fiberglass (older resins) don't mix. But there
are some folks out here (Dave?) that are running lots of ethanol through them
without issue.
Hypothesis: Dave - You are running premix, right? I wonder if the oil in the
fuel is "neutralizing" the bad effects of the ethanol. To that end, I wonder
if adding a "Marvel Mystery Oil" or Stabil or something similar would calm down
the ethanol effect on a non premix fuel supply.
There are people out here much smarter than me, does anyone have a thought on this?
Thanks.

| Subject: | Re: KF IV questions |
Hey Tom,
Thanks for the reply.
I do see the purpose of the large horizontal tab in between the two
vertical mounting tabs for the turtle deck. But there are also three
more small horizontal tabs forward of that position that are on the
upper tube that angles down behind the rear wing mount. They look like
you could mount a shelf or something there but that would block the view
through the turtle deck. They're also look too low to be part of the
turtle deck mounting unless an angle or something is mounted there.
Thanks again,

Phillips head 26S8-3 for the bottom rear cowl and 26S8-4 bottom front

Receptacles are all 212-12N.
Lock washers are all 2600-LW

These tabs are where you mount a short piece of piano hinge to attach

Chris,
Great video's. Thanks for sharing with us! I'm got to get me some VG's for my
5 (Vixen). I've got cracks in the paint showing up aft of the fuel tanks. I
wonder if I'm having the same fabric flutter you were having?
If anyone has VG's on a 5 (or higher), please let me know your experience with
them.
Thanks again!

and make sure the oil pump line up marks are correct. I leaned mine out just a
tad and got better plug color and performance. I do the same on all my snowmachines
as well. I measure the gas put in the tank, and the oil put in, then
figure the ratio and get it to match as close to 50:1 as possible. I know the
pump actually gives closer to 100:1 at idle, but 99% of the time the engine is
running in the 50:1 range so I set the adjustment accordingly.

I have about 40 hrs on mine with 3:1 gears and the IVO 72" 3 blade ultralight IFA
with NO issues. I played around going back and forth between 2.62:1 and 3:1
gears and have decided to stick with the 3:1 on floats. I put the SS tape between
the hub blades to check for movement issues, but so far, none have been
detected. I think the big issues were with the older blades that had the aluminum
inserts in the blades. The hub would tighten against the aluminum inserts
and would not properly clamp the blades.

I ran a 3 blade IVO on my first Avid which had a 3-1 gearbox with no proble
ms. I think you are supposed to have the crosshatch pattern on the hub to
better grip the blades. If you have the aluminum inserts=2C the hub shoul
d be slightly counterbored where the inserts are so the hub grips the body
of the blades. That's what I remember reading on the IVO site=2C and I ha
d no problems with the prop. Take care=2C Jim Chuk

| Subject: | Re: Gas Tanks (One more time...) |
Av8r3400,
I am not an expert, but based on some of the things I've read about ethanol I have
the following thoughts:
1. Ethanol (E10) does dissolve some fiberglass resins, but what I've read suggests
it was older fiberglass tanks made before the mid-80s. This is also the case
for plastic and/or rubber fuel lines, seals, o-rings, etc.
2. Phase separation, which happens when enough water enters the fuel, is a big
problem because the water and ethanol mixture is heavier than gas (and oil) and
would sink to the bottom of the tank. Which would cause a number of problems
- lower the octane of the remaining gasoline - likely have the engine ingest
a water/ethanol mixture because it would be at the lowest level in the tank -
have the water separate from the ethanol at altitude due to the colder temperatures
and then the engine would ingest straight water. And another bad thing is
with vented tanks the ethanol will tend to attract the moisture from the air.
3. Another thing is that two-cycle engines have a special problem with ethanol
blended fuels because of the fact that ethanol tends to displace oil on metal
surfaces reducing the amount of lubrication resulting in increased wear and tear
on the engine.
So, I'm not sure the oil/gas mixture is providing any protection or if the planes
flying with an ethanol blend with no damage have newer fiberglass tanks and
fuel lines which are less susceptible to the effects of ethanol. And I would
wonder what the ethanol is doing to the long term health of the engine due to
less lubrication. Again, I have no first hand experience with this and am only
basing my comments on what I've read.

Do you guys use any kind of fire shield on the fuel tubing? One of my mechanic
buddies had some extra lying around. You know, the orange sleeve stuff with
the little fibers inside (probably asbestos :( that you slide onto the fuel
tubing. I think it's used on hydraulic lines on larger aircraft. I'm not sure
how much good it would do if there were a fire though and it's ugly to boot.
