As I sit here and get ready to update, I wonder how many folks on the GG don
't know anything at all aboout the cowling.
The cowling is final back from the paint shop. =C2-He does good work; he's
just slower than molasses. =C2-His specialty is custom cars and hot rods
so he's always backed up on those. =C2-
Regarding the carb heat test: =C2-I may have mentioned on here that the st

e test is run, if it's hot outside, it's damn hard to pass the test. =C2-I
missed it by 4 degrees. =C2-I'm hoping for 30 degree air. =C2-Then I on

in the path, since the carb heat source is 'inside' the cowling, the FAA see
s it as affecting carb heat. =C2-I need to get a 90 degree temperature ris

the-way, I did find a couple of cold air leaks. =C2-Fixed those. =C2-
I'm going to install the first production cowling today. =C2-I need to cre

Gary,
OK, I'm not the smartest person in the world, but wasn't the carb
heat source inside the cowl for the original cowling? Why would your
new cowl, which has better airflow through it, cause a difference that
would make the FAA go bonkers?
It seems as though every obstacle you overcome, they throw up a new
one. Government in action. And people want to turn control of their
healthcare over to this government.....

Fuel leaks or two-seaters? ;)

don't know anything at all aboout the cowling.
The cowling is final back from the paint shop. He does good work; he's
just slower than molasses. His specialty is custom cars and hot rods so
he's always backed up on those.
Regarding the carb heat test: I may have mentioned on here that the
stock set-up with a PowerFlow didn't pass the carb heat test. The way
the test is run, if it's hot outside, it's damn hard to pass the test.
I missed it by 4 degrees. I'm hoping for 30 degree air. Then I only
have to do one test. You see, even though I didn't change anything in
the path, since the carb heat source is 'inside' the cowling, the FAA
sees it as affecting carb heat. I need to get a 90 degree temperature
rise out of it. On the stock cowling, I missed it by 4 degrees.
By-the-way, I did find a couple of cold air leaks. Fixed those.
I'm going to install the first production cowling today. I need to
create the installation procedure of the cam locks as I go. That should
be fun. Cross your fingers that I don't have a Grumman fly in on an
emergency.

I thought it was the four place that was plagued with fuel leaks not the two
place. What kind of fuel leak problems occur with the two place? First I've
heard about this...
We shall not cease from exploration.
And at the end of all our exploring

| Subject: | Re: Cowling update |
Their argument is: =C2-Since I didn't know what the pressure was in the co
wling lower deck (stock cowling) and since I changed the shape of the coolin
g air inlet and the shape of the cooling air exhaust ramps, I must have chan
ged the pressure inside the cowling and therefore changed the carb heat.
=C2-PLUS, since I use a ROUND inlet into the carburetor (on the baffle beh
ind #3) how can they be sure the air to the carburetor is the same (cooler o
r warmer). =C2-
Draw your own conclusions. =C2-For what it's worth, it was the stock cowli
ng that didn't pass the test. =C2-The FAA wouldn't accept being "as good o
r better than the stock configuration" for the testing. =C2-I have to meet
the current requirements of the FARs. =C2-
