I believe you, Opjose; however, there is something that scares me when I look at the picture of your Post #10.

I agree with Ken, because I know that vibrations and friction don't mix.

That is what I dislike about EZ's, that they are based on friction of the bolt against the pushrod, and also that the force is not applied in line with the arm.

I also use them for throttle and even nose gear.

As stated above, to use one EZ next to the engine is a no-no for me.
