Ax coldstart trouble

[manshe78]

Having a hard time getting my 1986 model citroen ax started. It turn over at once, but starts momenterly to hesitate, splutter, chugging and stall. It run pourly an ignite sometimes on 3 cylinders. After many attempts I get it to run, when warming up it idle very rough. And it runs very rich, like my other french cars. Lot's of soot coming from the exhaust. The whole car is shaking and vibrating.
I wonder what to do ??
My other french cars is hard started and runs very rich to, is this normal for French cars ?
