Last week I installed a new throttle system, different from the stock set-up &
I think better. It's a McFarlane cable assembly with cockpit adjustable tension
lever. Thx to Bud Yearly for his helpful document on throttle ideas, I still
his adjustable lever idea & idle stop but made one other change. I made two
aluminum washers shaped like the throttle box so that can't rotate this makes
it feel and work better. I found that larger friction washers worked better
too but we're hard to source so I made 1 1/4" phenolic washers with a hole saw.
The throttle lever pivot arc rises and falls causing the cable piston/rod end
assembly
to rise and fall too. I slotted the box to allow for this movement without
jamming.
This requires a seal to keep it clean in operation. Contact cement and the
finger
of a latex glove did the trick.
The cable run is short and direct, no bends greater than 45 deg. Friction is
very
low and McFarlane supply throttle springs 50% reduced tension. The 100%
& 115% stop will be on the top plate later.. It is a very sweet set-up and
is so smooth.
