Interesting,
I have one of hte older 5.8ci that was converted to the newer 102 then 105. IN both cases this happens. My friend has a 100 that was converted to a 102 evo and his does the same thing. I know of one other person on this board who has a couple of 110's I am hoping he see this and chimes in. I don't know if his does that or not. I have used a MSC, Mejzlik, NX and Menz propeller and they all do this. I will admit that the MSC does it to a larger degree and the Mejzlik which I am running now does it to a less extent.

Not with the BME twins.
You can drop the throttle to idle on landing, and it will idle down but still be running a little fast until after it is below flying speed. Never understood why but I have one and a friend has one and they both do it.

Sounds like you need to try a different prop. Engine spool up on a down line and braking are both a function of the propeller, not the engine.
This does not happen with my 110 Geistware, Silversurfer has flown mine a couple of times and he can verify this. It might be something with the timing or tuning.
doorvp--I would not be doing a lot of extended run ups on the ground with any large gasser. Make sure it runs reliably and put it in the air.
