What's the bottom line on cable throw?
A few years ago, I installed my "second" set of ASC cables for mixture and prop, because the originals were too short for the RV6A with the cables installed horizontal under the main panel.
Mixture would go from stop to stop, and the prop was close to the low rpm stop---- as I remember.
Then last week, I'm told that I should have about a 1/8" gap when the vernier knobs are pushed in all the way. Of course this throws may cables out of wack, no matter what adjusting I do.
Looking up archived responces to this problem, I find that the Van's cable throws of around 2.25 inches is a bit too short. One reponse from someone at Van's a few years back, was to adjust to full idle cutoff, and and let the full rich side, end up where it ends up.
This is fine for me, since I'm at a 4600' airport to start with, and never go full rich except for engine start. By adjusting it that way, I then of course loose that 1/8" gap, because the cable never hits the full rich stop on the carb.
Someone else had told me, that the 1/8" helps prevent the cable from locking, if the vernier knob is twisted while fully pushed in. I haven't experienced this, but it's possible I suppose.
Now for the bottom line. I see posting/replies on this forum from people who do the inspections, and some appear to want full stop to stop, and even an excess percentage of extra cable throw.
My plane is not inspected yet, but will be very soon. Is this just a case of ordering new cables for the 3rd time, to get that 1/8" gap? In all these years, I had never heard of the gap requirement till last week. But who knows, I never knew my gascolator had holes in the four screws for safety wires either...
I'm just wondering what so many others have done, and why Van's didn't supply cables with an extra 1/4".
