<p class="MsoNormal" style="margin-bottom:12pt;">Bob's got the
procedure. Use a .040" feeler gauge (or 3/16 drill) under the
throttle stop (1/5 of the throttle opening). Connect a 12V
test light to the fuse box and the top terminal on the throttle
switch. (Good example in Haynes Manual page 124). Light should go
out at this adjustment. Solenoid adjustment should be as Bob
describes and work smoothly-no binding. Hank</p>

Hi John,<br><br>
What keeps the O/D from disengaging immediately when you open the
dash switch is the 'throttle switch.' When the O/D is actuated
there is a parallel circuit that will keep the O/D activated until
you press the accelerator pedal, theoretically preventing reverse
thrust from damaging the O/D. The parallel circuit runs through the
throttle switch on the scuttle (firewall); it sounds like you need
to adjust it. It's a simple adjustment using a certain diameter--I
don't recall it offhand, but I'll look it up if you need it--drill
bit under the throttle stop levers. There's a small shaft off the
throttle mechanism that opens this switch--it's just a set of
points and a cam inside--with a lever with a pinch clamp. Just
loosen the pinch clamp, set the bit under the throttle stop plate
and tighten the clamp.<br><br>
If you O/D is actuating consistently within a couple seconds or so
then your solenoid, operating lever, operating shaft and ball
'valve' are correct. The
'stick-a-drill-bit-through-the-lever-into-the-housing' method is
notoriously unreliable; the proper setting is best achieved by
measuring the lift--IIRC, it's 1/32" but not sure--of the operating
shaft at the top of the O/D hydraulic section.<br><br>

<p class="MsoNormal">When I open

clockwise a bit to get the OD to engage when the toggle switch was
closed. This has always been the case and this issue is mentioned
in some articles.</p>
