Yves used a standard backplate on the 1.60 and mounted the needle valve on the fuselage. It may provide better adjustability as it will not vibrate aloong with the motor; it may make no difference whatsover, only providing a very handy adjustment.

The Cline Regulator will be mounted just behind the needle valve, not just behind the carburator. Yves has used it like that for about a year now with perfect results. The needle is not overly sensitive at all.
