I had it happen on my Grumman Tr2 within an hour of coming out of an inspection/carb rebuild. Grummans have a push-pull but also have a spring to lever the butterfly to the wide open position. I am glad it had the spring. My boss here at work had a C150 land in his back pasture 2 weeks ago because the throttle came loose and it WASN'T spring loaded to wide open. Seems odd to me that there would be such a setup on certified aircraft.
That is the one thing I don't like about 2 stroke carburetors such as the Mikuni. They are internally loaded to fail shut. Yes, I have flown them many times, but always with the thought of "what if". ___________________________________________________________________________________________ About a month ago there was talk about a better ignition system. Should we use more than one coil, or should we use a coil pack, or maybe we should use a crank trigger a certain way. The problem I see is that all the systems talked about have one problem. They require a voltage source. I have an idea that does not require a voltage source, but is "out there" so most will think I have "lost it". LAWN MOWER IGNITION. Simple, cheap, reliable, easy to set up, easy to have dual ignition, and NO VOLTAGE NEEDED. I have prepared myself for the dart throwing, so throw away.

I experienced the same thing several years ago 2 times ----I had a carb ice issue that bent the revflow spring. Had to kill the eng on final, better yet had to taxi at full power.

Good one Willie, a cool head and no problems, that's good to hear. My throttle is a simular setup, a spring pulls it to wide open and the cable is used to close it.

What to do when the throttle cable in your KR2 snaps in mid air. Last week Thursday I was flying "Shrek" around Phalaborwa just for fun at 1000 vt AGL. When I returned to the airfield, I noticed my speed was sitting at 160mph and closed the throttle to slow down. Nothing happened. The engine was still running at full power I joined on downwind and started preparing myself for an emergency landing. I called on the radio for ground assistance in case things got out of hand. The throttle design is such that a spring opens the throttle and the lever in the cockpit is to pull the throttle closed. In a way it is better than the push rod idea but anyhow. I planed to turn the magnetos off on a glide slope that I knew would take me to the runway without power. As it is, the KR picks up speed even with power off if the glide is not flat enough. The fire department was getting ready as I went around a couple of times at flat speed. During my last go around I pulled the cable housing out of the lever box (with my one hand) and managed to remove the metal cap over the cable housing end. This exposed 4mm of the cable tip. I clamped the 1.7mm cable between my thumb and forefinger and pulled the inner out. The power came down and I could use the accelerator like that. Now on finals I realized that at some stage I will need my left hand to apply brakes and cut the engine. So on short finals I let go of the cable, the revs shot up but before much happened I cut the engine at the magnetos. A perfect dead stick landing followed and pushed the plane back to the hanger. There are few things to learn from this. 1.. Don't panic and make hasty decisions. Take your time and plan your crash ( it may not be one) 2.. Practice engine off approaches so you get to know your aircraft and glide ratios 3.. Carry enough fuel so you can use it if you need to stay in the air longer than planed. 4.. Wear brown pants. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to [email protected] please see other KRnet info at http://www.krnet.org/info.html -- No virus found in this incoming message.
