For those of you running the Moki 1.8 - Perry VP 30 setup - do you have a problem with the engine coming back to a full idle after running at 100% throttle? On the ground I have great transition between idle and full throttle. in the air after running at 50% throttle or more the engine does not want to come back to idle quickly. It eventually comes back to idle, but takes about 5 seconds. It has nothing to do with the servo or linkage - it's the pump.

Any ideas? I'm got the pressure screw all the way out, and it still doesn't help.
