If it used to turn up to 6,000 or so and now it turns only 5,100 your problem is
not the prop. Leave the prop alone and look for something else. Is it a CDI
447 or points? If you have points, check them. After this long, might not be a
bad idea to do a crankcase pressure check. Or look for mud daubers in the muffler....
Taking pitch out of the prop is simply adjusting the prop to accommodate reduced
horsepower.

- Richard- good point.- I'll start with the carb adjustments.- I have
n't started it since putting a kit in.- I'm not touching it until I get t
he new parts from JBM.- Could it be a leak in the carb boot?- New one c
oming.

Subject: | Pitot tubes and air speed Plus Wind on the Alvord |
You may remember that I posted an email about the difference made in
indicated airspeed due to the angle of cut on the pitot tube some time ago.
To recap the idea came from John H about cutting the pitot tube at an angle
to allow a correct reading when landing in a three point stance. I thought
the idea had merit, and cut mine at about a 20 degree angle. I found that
angle was too much and lowered my ASI reading by about 10 MPH. I decided
that I would decrease the angle to see if that would better reflect what I
see on my GPS. I cut it to about 40 degrees this morning and went for a
flight to the Alvord and found that it read within about 2 MPH of what I
was seeing on my GPS. Much better, much nicer.
My conclusion is that your ASI can be adjusted by how much air pressure you
allow into your pitot tube. Perfectly round uncut tube allows the least
airpressure due to the overall smaller size of the opening. Longer the
angle, more opening to push air into the tube. Of course I could be wrong
about the airpressure, but I am not wrong that the angle affects the
reading on your ASI. Now of course I have a commercial static tube fitting
mounted on the side of my plane.
If your ASI is not reading correctly, give it a try. If you don't like it
you can always cut it back to square and not lose more than 1/4 inch off
the overall length.
As I said I visited the Alvord Desert this morning. We have had a greatly
reduced rain fall here in the High Desert this fall. So far here at the
house we have only had 3.25 inches of rain so far since November. That may
seem insignificant to most of you, but it is pretty close to normal here.
The Water this spring is about where it was last year in September. After I
made a circle of the Lake bed and was heading home I saw that someone had
tossed out a tire on the Lake bed. After cussing pilgrims in general I
noticed that there was visible evidence of the wind this spring.

Subject: | Re: Flying Bryce canyon and Monument Valley - Knowhow? |
Hi Mahesh -=0A=0AI haven't seen any responses to your questions, and althou
gh my experience is limited to three flights to Monument Valley and Bruce C
anyon, I'll share my experiences. As you know, I was flying a Maxair Drifte
r, not a Kolb, but I was flying with a 503, so there is one area of similar
ity. Depending on the flight, I was flying with either a Thundergull with a
503, a Carrera with a 503, and a Skyraider with a 447.=0A=0A=0A1. At Bryce
, both I and my fellow pilots used up almost the entire runway taking off.
However, we were taking off in the afternoons and evenings. If you take off
in the cool of the morning you probably would have an easier time climbing
. After rotation, I was climbing VERY slowly, at about 200'/minute. (I usua
lly climb out @ 900-1000'/minute.) Happily, Bryce is on a plateau and there
was plenty of time to gain altitude before the canyons.=0A=0A2. Land only
at airstrips in Monument Valley. There are a number of high plateaus that a
re tempting, but Monument Valley is Indian land, not federal park or monume
nt, and the tribe doesn't want you landing off-field.-=0A=0A3. Both Bryce
and Monument Valley are spectacular flying!- =0A=0A=0A4. When are you pl
anning on going? I was always there the third week in May, and by then it w
as already hot...once almost suffocatingly so. There can also be a lot of w
ind, so flying in the early morning and evenings worked best. Of my three f
lights to Bryce and Monument Valley, only once was it calm enough to fly du
ring the day.- I remember thinking that I'd never want to fly there betwe
en June and September, due to even greater heat and what that would do to d
ensity altitude.=0A=0AHave a great trip.=0A=0AArty=0A=0A-=0Awww.LessonsFr

As always great photos and the videos you share with us are wonderful.
The photo of the tire is impressive but I suspect that the tire was
floating during most of its journey.

I wouldn't bet on the floating part at all. If you blow it up and look at
it closely You will see that there is mud pushed up for about 10 inches on
either side. Here at the house, 36 miles away, we had several days with
wind as high as 69 MPH for an extended period.

Sir,
Attached is a photo showing how the impulse pump is attached on FireFly Five-Charlie-Bravo...
I also have a Facet Pump (electric), in line, closer to the fuel tank.
Good luck.
