Its actually almost 1-1 on the linkage. I must have done something right because no one (I showed the setup to a couple of experienced fliers) asked me to change anything except open the thread a bit because the engine doesnt cut when throttle-kill is activated. I will see it next week at field when I get more time with the airplane

I also had another question. I did the testflight with borrowed fuel- most guys use klotz gas lube (I think its KL305). After the flight I noticed a lot of black residue inside of the silencer. There were a couple of leaks from the silencer (screws) and that had gone black as well. It was similar to the burnt-on castor stains on the glow engines. Now, I dont want to open the "which oil" controversy again but is this natural and is it harmful to the engine? If so, how can I avoid it?
