Hi Glen,
I have the same problem on my XT912
I posted the problem on the microlighters.co.za egroup and the reply was : check that the jet on the inlet side of the fuel flow meter is all the way home.
To do this disconect the inlet pipe to the meter and use the back of a drill bit to press the jet in.
I tried this today, did not feel any movement in the jet,but it could have moved fractionally.
Will try checking accumulated fuel used tomorrow or Saturday to see if there is an improvement:blush:
