Duncan and all,
In my opinion, an adjustable stop at the throttle lever is important for
2 things :
- Allowing an easy fine tuning of the idle speed without disturbing
anything in the engine compartment
- Preventing any stress on the throttle linkage and carb, which is the
principal cause of changes in idle adjustment and carb synchronization.

French only for the moment, but a Frenglish version might appear soon...
FWIW,
