Blatantly obvious - but that is not an Escort Weber (Looks a little like a Falcon 34/34).... Do you have the fuel in and fuel out connections to the carb the right way round...
1 - Check you cam timing is not 180 out... (Should backfire through carb if it is and you have spark but it will not run...) If it is OK adjust static timing to 6 BTDC.
2 - Check you have spark.....
3 - Check you have fuel.... (Electric pump much easier, but mechanical will eventually pump through too)
4 - Check you have the the leads the right way round on the starter as if round the wrong way will fire, but die when you release the key...
5 - If all the above OK then you should get it to at least cough. Get a Mate to spray "Aerostart" or "Start You ****" down the carby when cranking... This will encourage more fuel to flow through and you should then be able to get it to run and tune it with the engine running...
Think
fuel and spark ....... fuel and spark ....... fuel and spark and if you have both you have fire.....
