The restrictor I have is a Rotax-supplied part that fits into the nipple that screws onto the clamp block (Part 17 in the drawing, P/N 840737).
The hole in a 0.65mm restrictor is nearly 3.5 times the area than a 0.35mm hole. I wouldn't do it. On what end of the hose you fit it would make a tiny (negligible) difference, flow-dynamic wise. I see that someone used a Rotax pilot jet screwed into a fuel nipple (http://www.rotax-owner.com/en/rotax-forum/3-4-stroke-technical-questions/1775-new-fuel-pump?start=40).Capture_2016-01-01.PNG (You do not have access to download this file.)

Hi Arthur,
It is supposed to be a Mikuni 35 idle jet. It is possible someone used the wrong jet.

Arthur, Roger,
Thanks for your replies. I got myself confused because someone told me not to forget to install the restrictor in the fuel return and (not knowing much) figured that meant I had to buy one and install it somehow. However, after talking to a Rotax parts person and seeing your replies I see that (being brand new) the part is already inside the banjo bolt (indeed, you can only both together as an official part) and I have no need to look for one.
Cheers
Paul

Arthur Gotz . . . Thank you in advance for answering . . . if you can and if you received this request.
I am having a CGS Hawk II custom built with a Rotax 912UL. Did you have your CGS Hawk built or did you kit build it?
What I do not know at this time is if my plane is the first CGS Hawk II being factory built with the Rotax 912 UL?
The company has changed hands recently and I am having difficulty getting an answer to my question from the new owner.
Thank you again for your time. mike.housewert@gmail.com
