Car Not Starting Noise

[piroska]

Sounds to me like petrol supply or ignition problems.

If it's a diesel engine then maybe fault with decompression system.

Once started does it drive and keep going perfectly well or not.

Remove air filter and try a start without filter, old engines clog up air filters with oil from positive crankcase pressure due to leakage around worn piston rings.

Spark fine.
Not flooding.
Yes it goes eventually and isn't running on 3 or anything. But try again and same thing.

Petrol not diesel. 

 It er does this sputter , well not quite. Whuff, whuff, whuff. try again, all the while the starter is doing is usual rrrr ok. But whuff whuff, finally after ages, Vroooom....
