I should have specified, that. Sorry, Av8r300.
I also use the Mcfarlane throttle. Some operators are removing the safety springs for full throttle return to solve the control creep during landing phase.
I did this. I have no problem with pushing the throttle to the stops WOT. I have been doing it for about 350 hours.
I also remove my top cowl at the end of the day. I inspect the engine compartment as part of my pre-flight/post flight. It is a 30 second job at most.

So I don't think I'll have a broken cable in my future but, that said, the springs are for the potential broken linkage in a dual carb engine. Removing them defeats a primary safety device in the unlikely event of a broken carb control.

But controlling the plane in a tight landing situation requires full control as well. I prefer not having to fight my plane to the runway.

The smoothness of the throttle operation without the springs is a remarkable plus for throttle control.
