Project Log: Thursday,

Taking advantage of a slack moment, I thought I'd
quickly hook up a throttle cable between the engine and
the new control to determine just how far the throttle
lever needed to travel. Adequate clearance for the
throttle handle was at issue; I needed the practical
illustration of the maximum travel to realistically help
determine the final placement of the control unit on the
console.
In order to effect the test I had in mind, I found I had
to first change the orientation of the inner workings of
the control unit itself. Since my engine required
a "pull to advance" orientation ( i.e. advancing the
throttle lever pulls on the cable, which in turn pulls
on the throttle arm on the engine), and the control came
standard with a "push" arrangement, I needed to switch
things around. This was straightforward enough,
but took some time.
In the photos, note the different positions of the round
top piece with the pin (inverted in the second photo)and
the "V"-shaped assembly directly beneath, also inverted
to convert to "pull" operation. |

Similarly, the simple act of hooking up the control
cables, even for a brief actuation test, required more
or less installing them as they would be in the final
version, which took a few minutes, mostly fumbling with
the small screws and nuts on the cable clamps on the
engine. I eventually hooked up the sample
cable and actuated the lever to full extent of the
throttle arm on the engine. The lever ended up a
bit less than its full possible travel with no cable
attached, but was still substantially forward, ending
with the tip of the handle 1-2" above a horizontal
plane. |

With the information I needed now determined and
recorded, I disassembled the cable and various parts,
and stored them away till they'd be needed for final
installation.
