Hi again. Seems the topic on the airfoil got a bit heated as RCKen stated. Anyway I have a question regarding the pushrod which operates your carb/throttle.

Little background. We went flying today - made it a picnic day. I ran out of my 5% fuel and put in a friends 15%. Adjusted the engine etc. Anyhow, I took it off and in the middle of the flight I had no control over my throttle - nada. It was running full throttle and I couldnt cut it - used trim and throttle cut, but none would work - which we found out why after landing. Well there was just one way out of this one and that was to fly it until it runs out of fuel. So it did after about 10min in flight. Deadsticked it in, for a pretty decent landing if I may add.

What happened was, the little screw/plug thingy which is on the carb where the pushrod gets tied down to broke off - at WOT can you believe. Now, does one need to have that plug thingy (have no idea what it is called) or can one just use a Z bend?
