Details on this mechanism required please
Hi
Changing out the T/B gasket and decided i'd like to know what this device contributes to the cars operation.
Looks like it activates upon throttle release, has both an adjustment on the base of auctuator arm and vaccume.
Can someone please tell me what its called, what its function is and how to correctly adjust it.
Can't find anything in the PDF manuals I have.

Congratulations youve found the Flux Capacitor....
looks like some sort of Dash pot device.
Nothing like that is on the JB/JD style Tb...

Cold start!
When the engine is cold, this unit pulls the throttle to run the car about about 2000rpm. As it warms up, the little lever pulls out and the idle returns to normal.
The pellet in i've highlighted in the pic you'll notice is connected to the water supply through the engine. This pellet normally gets old and jammed, hence why it's not working!

hmm, I think that its seperate from the cold start,
I can see the water pellet and how that works, it pushes up when warm and releases the throttle slightly.
This unit appears to be seperate as it has no linkages to the cold start "pellet" and isn't capable of pushing the throttle in any way as it can only move in the direction away from the throttle.
The throttle opens clockwise, the pivot for this device can only move anti-clockwise away from the throttle, but can be adjusted so that the arm can be pushed when the throttle closes hence altering the little diaphram up the top to adjust something.
Any other suggestions or confirmation? Specific operation descriptions?

that`ll be the dash pot mate,
I personally throw this thing away when it sh-ts me and havent had
issues without it..................................(I think)...................
when you back off the throttle the engine gets high vaccum and
the dash pot will pull up causeing the motor to rev to 2000+ for
just maybe 2-3 seconds, activating the EGR (I think) and it does it when you change gear (you know ?????????????)

You can actually adjust old & tired ones - there's a hex-head brass plug on the firewall side of the dashpot (between the round bit and the square bit) which you can loosen. This will bleed a little air from the dashpot and allow it to operate better. Loosen it a very small amount at a time (say 1/4 turn) until it operates correctly, and then put a small dab of glue on it to make sure vibrations don't affect the position.Chryzla wrote:but when it gets old and tired it takes a month to let the revs drop...
