Hi All, i have a tempra 1993 1.6 and i think after a carb cleaning at the garage that i did a few months ago , they have attached the vacuum tubes wrong or so. I know that when you turn on the air conditioner the RPM should rise a bit. It is done by pulling a small lever from the back left side of the carb by an air pressure. but it's not working at any condition. When i lift it by hand i see the RPM rises. Also i have replaced all the tubes with new ones. Changed it one by one like it was in order not to make any mistake. Can anyone plz send/show me a diagramm how to connect them correctly.

Thanks.
Sry for my bad english.

I am sorry I think I can't help you since I have a Tempra 1.6 carb but with no air conditioning

Hi,

The diaphragm that pulls the accelerator lever (to supply extra fuel when the A/C is turned on) you are referring to has its vacuum hose connected to the left side (the side with the electrical connections) of an electro-valve positioned on the firewall, just behind the carburetor. This electro-valve has two electric wires connecting to it, and another vacuum hose (incoming vacuum) on its right side. When the A/C is turned on, the wires supply 12 volts to the electro valve and the valve opens to admit the manifold vacuum to the diaphragm.
The incoming vacuum hose of the electro-valve should be connected directly to the inlet manifold vacuum, probably through one or two T adapters and hoses, that also feed other vacuum clients. Make sure however that when you follow the T adapters and hoses you can find a path composed of hoses and adapters only that finally ends in the inlet manifold.

If the vacuum tubes are not messed up, and the electrical connections to the electro-valve are also OK, then the diaphragm or the electro-valve is bad. To see if the electro-valve works, simply disconnect the outgoing hose from the diaphragm, and see if you feel no vacuum with A/C off, and vacuum with A/C on.
To check if the diaphragm is bad (which would be my guess if all the connections are OK), just connect a vacuum hose to it and apply some vacuum with a vacuum pump – pump once or twice and then stop. If you do not have a pump, use your mouth, as if the hose is a straw, and then hold your breath. The diaphragm should pull the accelerator lever and hold it in that position. If it does not pull, or if it pulls but then releases by itself within a few seconds even though the vacuum pump was not disconnected (equivalently, even though you are still holding your breath), then it must be leaking and should be replaced. I am afraid that these diaphragms are hard to find.

Don't worry if you have to use your mouth. You will not inhale anything toxic. At worst, you may feel a slight trace of an oily taste - nothing to worry about.

I haven't understood, the carb now installed is not the original one?
I have no schematics, at best I can try to make some photos to my carb for showing how the various pipes are connected.
