i have one on my carburettor but it is not connected to anything?
the yellow wire has been cut and the carburettor is making a popping noise as the auxillary valve jumps up and down
i have mechanical secondaries and i have done a carb clean

should this dieseling solanoid be connected?
the engine does not run on but does sound kind of buggered in idle

Yeah it stuffs your idle when not connected, I used to modify them somehow but its been 12 years since I touched one and can remember what I did, sorry.

12 years since you touched one levey... pfft( your infamous words), supose yours doesnt count.

yeah it needs to be connected other wise idle is rubbish and wont run real good at idle. i hated stock carbs, been a while since i touched one as well

Even yours? I thought so Mik, that would be a wire to an earthing point I presume.

i thought it was powered. now lets not start talking male to male conections nige

Being a solonoid you are probably right Mik, I must have been thinking about sender units!

how about we sender you somewhere?

oh your in perth, sentence served.

pretty sure it powered as block is earthed to car (so carby too)

This is a new dimension of whoring : help & whoring at the same time!
But yes you have to be right about the positive to the solenoid wire.

All the whoring aside
Mine has the same problem, anyone know where wound I get one from (anti-dieseling valve that is)?
I just got my ute and it was running pretty bad, had the throttle screw wound out 7 full turns and the idle right up. I'm figuring that this was done to try and compensate for the anti-dieseling valve not being connected, hoping so anyway.

Cheers

The anti dieseling device is a solenoid so it needs power to operate. It needs this power whenever the ignition id 'ON' but at no other time.

The purpose of this device is to allow a spring loaded 'needle' to plug the idle circuit whenever the engine is turned off. Even if the plugs are glowing white hot, this device cuts the flow of idle fuel to the engine & it can not 'run-on' without fuel.

It also prevents unburned hydrocarbons from entering the exhaust system, to be ejected into the atmosphere on the next startup.

If it is disconnected, the idle circuit is closed & it is necessary to increase the idle speed so that the engine can draw fuel from the transition port. This fuel is calibrated to be mixed with the idle fuel for correct mixture, but without the additional fuel from the idle port it is running lean, & therefore, badly.

I have been using a stock carb on my 1200 for years & I love it.
It is correctly sized for smooth running, great economy, & peppy performance without being over the top.

Those clever little Datsun engineers definately knew what they were doing when they designed these.
