| Subject: | 912ULS: Carburettor and Airbox venting lines |
I am going to install the Rotax 912ULS in my CH601XL soon. The new installation
manual from BRP-Rotax (Version 1 / Rev. 0, May 01/2007) is quite straightforward,
nevertheless I do still have some questions:
- The manual states on page 92 that the carburettor venting lines should be routed
into ram air or vacuum free zone or into the airbox. Drawing 59 shows the
connection between carburettor vent and airbox. Ok, I understand that...
- Then the manual states on page 102 that the airbox venting line should be also
routed into ram air or vacuum free zone OR INTO THE AIRBOX. Well, the drain
is FROM the airbox, how comes that I should reroute TO the airbox???
What is common practice? Connect carburettor vent to airbox and then airbox vent
to some place below?
Thank you for any advice!
Cheers Martin

I ran both my airox and carb vents separately down the engine mount into t
he slipstream.

Hi Martin,
I have a Flight Design CTSW and the carb vent lines run into the airbox and all
other lines from there run down and out under the bottom cowling just barely
in the air stream. (oil vent line runs out at the same area)

Thank you for your answers!
I was just wondering if it is a wise idea to run the pressure sensitive carb vent
lines into the slipstream. Homebuilt.org and I think also Lockwood say it is
not the best setup.
Nevertheless you don't seem to have troubles with this configuration. I will follow
Roger's instructions.
Cheers Martin

Hi Martin,
My hoses come down inside the cowling and actually stop right at the bottom. They
don't actually protrude out into the slipstream, but right up to it.
