Default SU HD-8 Carberator Help

My car has been stored for several years.
The carbs were completely rebuilt with shaft bushings.
The carbs dried out and when restarted the carbs run very rich. Will they need to be completely kitted or will a partial kit do the job?

Giovanni,

I've moved your question from General Tech Help to XJ6 & XJ12 Series I, II & III forum and added vehicle details to your post.

Members here with the same model will be able to help.

My strong suggestion would be at the very least, NEW main jets.

The diaphragm attached to the bottom of the jet COULD be quite cracked from that drying out, and fuel will leak past it, and drip on things. One of those "things" is the distributor, oops, spark followed by flame, NOT good for Jaguar.

Every thing else should be fine.
