My mechanic is telling me that carburetors needs to be rebuild but I don't really trust him.
The problem is that the car (Datsun 260z) is very hard to start and is not drivable because fuel is mixing with the oil. If you take oil cap and smell it you can feel smell of the petrol. He is saying that carburators needs to be rebuild but I wouldn't be so sure because when I bought the car there was no such a problem and since I bought it the needles in carburators were changed, the valves were polished, plugs and plug leads changed and after that that problem came out.
Do you know what might be the problem and how to fix it or at least check it what it can be ?
Thank you for reply
