Glenn,
The throttle slot is cut by the builder. Follow the build manual and
consider following the Rotax manual also. I build into the 914s a stop
for 100% and ensure the forward slot will just bend the throttle cables
at full 115%. For idle, I put a #10 nutplate and a 10-32 flat head
screw (a 525 10R-8 to 12 will work also) which is sufficiently long to
stop the throttle just as the carb idle stop is contacted. Those with
vernier style throttles have a bit of a chore. You must come up with
some method to stop from bending the idle stop which is a very common
rough running and engine failure problem.
Please consult the manual and pull the throttle box from the cockpit
module and get the throw correct. At the end of a project, when our
attention to detail should be peaked and our research impeccable, we all
make minor mistakes. Double check to be sure. I have never had a
problem with the stock throttle operating flawlessly.

Setting about carb' rebalance (912) we were puzzled to find the setup
unable to achieve full throttle arm position at the carb - i.e. we are
about the width of a 1 UKP coin short of the full throttle stop ~3 mm,
and in violation of the rotax setup instructions.
Tracing this geometrical conundrum back it appears that the slot in
the throttle 'quadrant' plate in the cockpit is too short by about ~2cm.
Has anyone encountered this? The build manual does not indicate
dimensions of the throttle lever, so either there is a mal-position of
holes in the arm, or the slot was too short to start with, or both. We
have not yet opened the throttle lever box. The aircraft has over 400hrs
of normal ops, but we worry we might be a tad short of full rated T/O
power.
There was a small stop installed at idle (cockpit), however with this
removed the problem remains.
