Set carburettor there 16l/100km…

16l/100km at 55ps… ( Hi Leutz! I have really old (17 years) Mazda 323 with 55hp 1.3l engine and automatic transmission. the problem is that I drive like ne oma and at the moment up to 16 liters (NO WITZ!!) consumption if the car has times n very bad day… I was still traveling with 8-10 liters in the summer and therefore the opinion that can’t really be with 55ps. unfortunately I am not a car screwdriver but I thought that it must be the carburetor because I have to change oil, oil filter r, air filter, spark plugs and ignition cable everything has been renewed and it underscored getting worse! I looked at the candles and must say that they were quite rusty what I really shouldn’t be, so I decided that the carburetor ever needed a little love because the engine might just be running vieeel too fat and therefore is acidic without ending. hope there on such theories as the throttle valve maybe somehow no longer closes even though the engine has become warm and therefore simply no air gets aba how can I test such a thing?? maybe someone can tell me where and how to set the thing because I have to drive at the sprite prices otherwise really soon s-bahn!! please report to me if jm has any tip!!!
