82-8300 rpm when new, 85-8600 rpm after ~30 flights.

Magnum #1, OS-F or YS plug, ES-2C140L90 pipe set at 23-1/4" baffle to 
plug, stock Mac's 2-1/4" rise header, and an APC 17x12 prop.  The 
Webra MC (mixture control) carb I'm using gives a dead linear 
throttle response with NO jump onto the pipe.  Setup this way the 
motor throttles exactly the same as a DZ but with better performance. 
With the stock ProMix carb it throttles a lot like the OS (rich in 
the mid range).
