Rob,
Congratulations on the completion of your HKS project. I'm coming up on a year's
flying with my HKS powered Firestar II, and have had zero problems. It just
works - smooth reliable power on demand, plus low fuel consumption.
How about some pictures?

The ASI is a pressure differential gauge. No positive indication means
it is not sensing different pressures at the two sources.
Possible causes include:
Blocked pitot,
Static inlet in same airstream as pitot,
Gage is screwed up internally,
Pitot inlet tube disconnected at the gage.

Mike, good thing you inspected. Looks like you guys have uncovered a
problem. There may have been
a bad production batch with no way to know who got the bad ones. As
far as ethanol goes, unless
you have been using only avgas you have been exposed to ethanol.
Nearly all auto gas has some
in it now. Around here there is no pump labeling either.
Ethanol is a very universal solvent when in contact with polymers.
Very similar to acetone with
regard to both water and mineral solvent mix capabilities.
There will be more problems showing up down the road with both
aircraft and autos.

More stuff:
Marvel-schebler has had a similar go-around with float materials, in
some cases
having owners change from original metal to plastic, back to metal
and then back
to "new improved" plastic. ( I would have stayed with the metal -
screw the AD)
The current favored plastic is delrin or POM (polyoxymethylene)
which is a resin used as a binder in solid structures with either a
glass or teflon fiber filler.
The Bing floats look like foam with an epoxy cover. I would inspect
them frequently.
No plastic in my old solex

Rats ! I just wrote a long response(very slow typer) and added a couple pics.
I went to preview it, and when I pressed the back arrow it was gone. grrrrrrr.
I fly in coastal British Coumbia ( read BIG TREES everywhere), so I feel I need
a four stroke. I like the 503, and if I flew somewhere more forgiving I would
be happy with it. There are really no airframe mods to be done, you just
make an aluminum adapter plate.
There are alot of decisions to be made along the way( you dont just bolt it on)
(C of G, thrust line, gearbox, electical location, etc.) If you're a mechanically
inclined (as opposed to "mechanically declined") idividual it is not that
hard.
The finished package (fairing, instruments, brs, custom 12 gal tank, alum leading
edge wrap wing, etc.) weighs 465 lbs. The gross is 750. Twinstars in the
past have been flown waayyy over gross. A guy named Rick Trader flew a twinstar
to Alaska and back loaded between 1000 and 1110 lbs !!! I will fly my plane
for a year or so, before I even consider taking a passenger. At that point
I will load it up heavy, and go high, with a couple chutes, and beat it up a bit.
If it survives that I MIGHT take a light passenger on a still air evening.
[Wink] cheers, Rob

Has anyone asked what Lockwood or Ronnie Smith think about this
condition?
As those guys are Rotax experts, maybe they've seen this before and can
offer an explanation or solution.

How do I adjust the pitch on my 3 blade Ivo prop? Do I loosen the center nut and
turn the center shaft right for more and left for less pitch?
Is there a certain torque setting for the nut? What size socket is needed?

Mike,
Thats what mine looked like. One was in much worse shape with large bubbles. They
do seem to like to bubble around the edges.

yep.! loosen the nut with a big crescent wrench..:-) Then turn
the screw with a suitable round bar or screw driver for the desired
effect..I never try to remember the correct way...Easiest is to
record your current static max rpm's and then adjust the prop for
effect... I set my three blade on the 447 powered pup for 6200 static..
I simply tighten the nut as I please and then install a tie wrap
through the hole to avoid loosing the nut should it come loose..
I think it is a mistake to run an ivo prop in its neutral
position with no tension either pos or neg on the tension rods...My
thought is that it allows the tension cams to hammer back and forth
in the slot in the adjusting screw... maybe causing the occasional
tension rod break through..? Certainly has to contribute to the
flattening of the cams...Herb

Thanks Herb.
Jack I did look at Ivo's website before posting however it did not tell how to
adjust the prop. It explained how it works but not how to do it.

| Subject: | Airport Attitudes |
Kolb Friends -
I encountered a little incident at my home one evening this week that
made me realize that there are STILL people out there in charge of
airports who regard ultralights and other very light aircraft as nothing
more than an annoying nuisance. Which is sad.
I was flying right about at sunset - beautifully smooth air and
spectacular fall colors in the foothills. Near the end of my flight, I
saw a powered parachute flying near the airport, so I swooped in closer
to get a better look. I recognized him - this guy flies from his own
property a couple of miles from our airport, and I often see him flying
at sunset when the air is smooth. He and I recognize each other's
aircraft, as we are often in the same local airspace together with the
same flying goals in common: To enjoy the simple pleasures of low-cost
recreational flying. (p.s. - that's one of the things I love about my
Kolb - I can slow down to *almost* fly in formation with a powered
parachute. Almost.)
After I landed and pulled up to the hangar, I got out of my Kolb, and
saw the parachute guy flying toward me. He was pretty much flying right
down the runway, about 50' high, then turned to fly right over where I
was parked. I waved at him, and he waved back. I could see the smile
on his face as he was waving.
Moments later, the airport manager drove up to me and asked, "Do you
know that idiot? His type are not welcome here." I was not about to
narc on a fellow recreational pilot, especially if he wasn't doing
anything wrong or unsafe. I just said no. (I'm certain I would be
viewed by our airport manager as one of those "dangerous" ultralights if
my Kolb were not N-numbered.)
So I guess the point of this message is, fly safely, and obey the rules.
There are still people in charge of airports who do not wish us to be
part of the mix, and will do what they can to have us thrown off the
airport.

Grant,
The way I remember the direction to turn the center shaft is relating it to
a vernier throttle, common on Cessna. Turning it to the right produces more
RPM.
