I am looking to order a McFarlane Vernier-Assist throttle cable and noticed that the stroke is 3.5" but my airflow performance FM-150 only needs 2.5" of stroke.
I also noticed that ACS products makes RV specific control cables with 2.25 or 2.5 stroke for the prop and mixture.
What I don't understand is why there are custom shorter stroke cables for RV's. Wouldn't a standard A-750 control (with a 3.375 stroke) work on an RV with the cable hitting the stop on the fuel servo making the control stop at 2.5" ?
Please help me understand why it would be desirable to have a custom cable with shorter throw when a cable with a longer throw just simply stops short from coming all of the way out.
Thanks,
Matt
