The problem is caused by the fact the throttle stop isn't strong enough
to prevent it being flexed by operating the throttle from the pilots
control.
As explained by others an additional stop on the cable is recommended.
The simplest and cheapest way of fitting this is to use an electrical
screw connector removed from it's plastic.
These connectors are readily available and known in the UK as 'chocolate
block'. See attached pictures (apologise for lack of clarity, phone
pictures).
The pain when fitting is the fact the end of the cable needs removing
from the cable to fit it.
This additional stop prevents the cable from being pulled too far and
bending the throttle stop arm which holds the adjustment screw (at a
strange angle).
The throttle stop arm is one of those Jabiru issues that isn't really
applicable to a Jabiru plane throttle so hasn't been 'improved' by the
manufacturer.
During the early hours your Jabiru engine will loosen up and the idle
will increase, you will have to make a few adjustments in the first 100
hrs. There is also the issue of the idle mixture which if not set
correctly will make the idle running sensitive and liable to stop at
higher revs than you would like.
An 850 rpm idle on finals will give 1000 rpm or more, revs that will
make many aircraft float along the runway nicely (tell me about it....).
