REBUILDING A CX2400 CARBY

Check the number stamped in the base of the carby body.  You will need this to order in the required carby kit.

I knew the top gasket in the carby was broken up, and the car wasn't running very well so I decided to put a carby kit through the carby while it was off, and check it out.

Before you remove the carby start the engine and let it idle, pull the wire off the idle cut off valve(anti diesel valve) if you don't know what this is it's the only electrical connection to the carby. The motor should stop.  If it doesn't your idle cut off valve isn't working, even if it's clicking.  You'll probably find your car wasn't idling very  well, and running rich.

First remove the carby from the car, remove the four nuts at the base of the carby, undo the choke cable, pop the throttle linkage off, and remove the 4 nuts the hold the air cover on the top.  Note the way the various anti pollution pipes were hooked up, and label them with masking tape if you don't trust you memory.

Buy some carby cleaner and using a tooth brush give the outside of the carby a good clean, most of the red staining will spray straight off.

My carby after I pulled it off.  Note how dirty it is especially around the accelerator
spindles, they will need checking.


 

My carby once stripped.  I only have a very cheap digital camera, so the quality of the photo's isn't to flash.
