I finally got my car back together and I was about to say that it is completed.  Only took me 7 years
 
But....the bugger wouldnt start.  I had my auto electrician come out and I had a loose wire which he fixed up but it still would not start which he said was due to stale fuel.  Same fuel in the tank for about 3 years. (he was able to start the car by squirting some carby cleaner through a vacume line).
Anyway, he suggested replacing the fuel and the spark plugs.  I have just finished doing this and it still does not start.
My question is, how bad is stale fuel.  I pumped the fuel out and then put about 20 litres of fresh fuel in.  I then cleared the lines by running the fuel pump and collectind the fuel near the fuel rail.  There might have been a litre or 2 of stale fuel still in the tank, would 2 litres of stale fuel mixed with 20 litres of fresh fuel be enough to stop it starting?  Do I have to drop the tank
