Fully closing the throttle doesn't always shut off my MVVS 26cc gas engine which makes the transmitter's throttle cut feature ineffective. It may not stop even when pulling the throttle trim back until the servo buzzes while it ''crunches'' the carb throttle plate hard against the stop....could it be that some carbs have that little notch at the edge of the throttle plate that prevents the air from being completely shut off?
Same thing here on my RCGF 26cc in my P-51, my first and right now only gasser. I have tried until I'm blue in the face to get the engine to stop by using full down trim on the throttle, 'kill' via a trim switch and tx setup, you name it. This method has always worked fine on my Saito's.
So, I ended up putting a servo on the choke (which I like even if the throttle trim worked to kill the engine) and it works fine to kill the engine. But, I am NOT comfortable with only having one way to kill the engine via the tx. I fully embrace the keep-it-simple concept, and don't like adding weight and failure points, but I'm going to add an opto kill switch.
Now, any suggestions on how I can get the engine to shutoff with the throttle trim? This has me baffled...pun intended
