Hi Juergen,
In our monowheel XS with Rotax 912S we use the Skydrive carb heaters.
We originally had them on all the time, but had some trouble with
restarting the engine about 15 minutes after shut down, so we installed
a water valve to allow turning off the water after landing, to keep the
carbs cooler on the taxi back to the hanger.
We did some climb testing on a hot day to see if there was any
difference in performance, heat on vs heat off. There was no
difference, at least in our plane.
Regards,
Terry

Subject: Europa-List: Lack of power with water heated carb body
mountings
Hello again,
after eight months of modifying my classic I am back in the air again.
My flight inspector said after he test flew the aircraft: "funny
aircraft but be careful with your payload, it is absolutely not
overpowered!"
Well, I thought that impression you get when you are used to turboprops,
like he is.
But today it was me who made the same painful experience.
It is not so easy to realize the lack of with a CS prop but my europa
now climbs solo as before with passenger and it seams the have all
shortened the runways.
After my last flight today I opened the cowling after half an hour on
ground and even the top of the carbs have been that hot you could not
leave your hand on them.
Now it is clear for me: I need a stopcock to use the hot water only when
needed.
But I wonder if it is only the heat that is responsible for the lack of
power
or also the longer suction tube ( don't know the right English term).
Has anybody made similar experiences.
Tomorrow I have my test flight with the flight instructor but I will not
let him in before I have got it fixed.
Thank you
Juergen
