Yes still running the same jets,
guess you know more about my plane than I do, I like that idea of
having injection and a carb for a backup, with that setup I would not
bother with the air ram as you can use the injection for high
altitude.

Ken;
In a note you posted 04 Feb 04, you said to set up with 200 main gas
jets, 155 main air correction jets and F-7 emulsion tubes and it
should work fine. Are these the jets you are using currently, or
have you went with something else. When the manual comes
I'll take a look and see what I have. I have the photo you
posted of the ram air setup, looks quite simple. It looks like
with a set of high pressure pumps and electric fuel valve that I cam
use the Weber and, or the fuel injection on demand. I have the
fuel injection system and the plumbing is in for the fuel return to
the tank. Will start with the Weber as project must fly in
spring. Working on the wrong end of the time curve at 69.
Thanks for the info. From the farm, buried in

That was probably me,
its not a choke its an air ram that increases the air pressure in the
Venturi in comparison to the float bole so the Venturi draws less fuel
through the main jets, when I get by the airport tomorrow I will shoot
a photo of it and also get the jet numbers I am
running.

Hi Lynn,
I read some time back where a builder jetted a DCOE to run
with the choke on at sea level and used it to lean out the mixture at
altitude by backing off the choke. Do you have any knowledge of this,
or other methods of variable mixture control for Weber carbs in
aircraft?
Thanks for your comments, Dave McC

that show all you need. I have been using one since 1980, if you have
