Gentlemen:
Several comments that I did not include in a recent e-mail.
The engine stoppage will occur any time or place that one aggressively brings the throttle back to idle. This will occur in the air when practicing maneuvers, or on the ground when another plane or object will cause one to close the throttle rapidly. Think ahead and be gentle with the engine.
We also had a problem with a loss of up elevator feel during short landings and practicing stalls. Purchased the Ray Allen electric elevator trim from Lightning, and this made a major change in the control inputs. Should you have this situation, this is a good investment.

Ray, what you describe below shouldn't happen you should be able to
'smartly' close the throttle without the engine stopping.
Smooth control aside you should be able to make reasonably aggressive
throttle reductions without it stopping.
Check the idle mixture and idle settings again. Read the Bing section of
the Jabiru manual, it's all there.
If it still happens check with your dealer.
Just MHO!
Regards, Clive

I know we’ve covered this topic before but without a throttle stop to prevent excessive force at the carb throttle arm a strong pull on the throttle will actually bend the throttle adjustment screw on the carb. There is a metal tab attached to the carb that holds the idle rpm adjustment screw. This is a stamped piece of steel but there is more than enough force that can be applied, especially with our throttle arm extension, to bend this stamped piece.
A throttle stop applied as Nick detailed in previous emails will prevent excess force from bending this metal piece. If you do not have a throttle stop installed then you should do so soon to prevent bending the idle adjustment tab or bending the cable attach bracket on the carb.
