Dan,
There is a PDF document on how to do this at this website. http://www.xairireland.com/ go to XAir - Hawk - Downloads and you'll find a fuel flow document for the 2200.
I'm currently building one of these with a 2200a on the front - but I haven't got
as far as you yet.
Good luck.
Ian Wilson

I just finished Building the X-Air H in February that's a nice little
airplane I am impressed with it , it went together quick and it's a rugged Design
compared to a lot of planes of the same construction design and I hope to be
building a lot more of them and The 2200 Jabiru wow that is a nice piece of
Machine work and it is so smooth running compared to the Rotax that's my
first choice for an engine on my own plane now
