u r rite that fule older to 6 months make problem. but i did cleaned the tank, changed the fuel pump as that was not in gud condition, and ofcoz the petrol was awful. good thing was that i didnt try to start car on that petrol as that wud cause troubles to carb and engine too.
hence the petrol issue isnt there.
can u tell me what is the "KIT" in carb, as a mech said kit change krwain...
