It does make a difference =93 on our setup with the engine idling
normally (carb throttle arm touching the carb stops) we get 2,000 RPM
=93 apply back pressure and the RPM drops to 1,700 RPM =93
release pressure and the RMP goes back up. The distance between the
throttle lever and the backstop is about 2 =93 3 mm when no
pressure applied.

Duncan,
You've got me there. Surely if you have already pulled the throttle back
to the stop on the carb., pulling the lever any more will not make any
difference at all. Unless I am missing something.

are now flying again from our previously waterlogged airfield, so
another week should see us over the magic number, and loving every
minute of it)

Whilst complying with the LAA requirement for a throttle stop, it's
useful to set up the cables so that the carb stops are reached first,
followed closely by the stop on the throttle lever itself if the lever
is deliberately pulled closed against the throttle lever stop. This
limits any excess strain that can be applied to the cables, but provides
a useful facility to temporarily pull down the idle speed in flight
(which in any case will still always be well above the static setting,
as the forward motion drives the prop). As soon as the deliberate
backpressure on the lever is released, 'normal service' is resumed
This facility makes a usefully large addition to rate of descent and is
helpful for landing in to short strips; it's like having an airbrake!
