 Posted: Sun Feb 17, 2008 5:06 pm Post subject: XL / Jabiru Dual throttles |
 |
|
I'm working on my firewall right now and trying to see how everything is going to fit. I bought the dual throttle kit for the Jab 3300 and in checking the installation instructions find that they don't exactly apply in my case.
From what I can see, earlier XL's had a flat shelf to which the dual throttle was installed and a metal tab added to which the center cable to the carb was fitted.
My XL has a beefed up shelf with angles added to the top so I need somewhere else to attach the thottle cable to the carb.
If there is anyone else out there who installed JabiruUSA's dual throttle kit onto a shelf like mine would you mind telling me what you chose to do?
If I just attach the throttle cable to the shelf itself I should get about 45 mm of cable travel. Is that enough?

Tim,
The new HomebuiltHelp video on the Jabiru covers this. But even
with the old shelf, I had to re-configure the dual throttle option. And you
can call Pete or Ben for help too. In short, the center throttle cable goes
through a hole in the shelf down to the carby. I picture of my installation
in progress is attached.

Tim,
I don't have much to add to what Jeff already said other than to add a few close-up pictures of mine with the new firewall shelf configuration. I did not measure my degrees of motion, but there is enough to fully actuate the throttle from stop-to-stop with some to spare. Also, the brass cable adjuster going into the carby needs a bend to avoid the nose gear strut. As recommended by Jabiru, I used a tube bender. Just make sure not to make your bend right where the brass transitions from thick wall to thin wall. I will break there if you do. Look down the inside of it to see where it transitions.
Good Luck,

Dave & Jeff,
You guys are outstanding! Just what I needed to know and see. I really appreciate the help.
Tim
PS. I ordered the homebuilt help DVD but it hasn't arrived yet.
