1.9DG engine, pierburg carb
I turn the key and it does everything but start.
Starter turning over OK.
fuel getting to the input of the carb OK so I assume the fuel pump is OK, fuel in the tank, battery fully charged, air filter not connected to carb
so far I have :
*replaced the fuel filter, ignition coil, rotor arm, ht leads, distributor, spark plugs (they were all looking a bit suspect, all bought from from mr baxter so I know they are OK)
*removed and cleaned the carb fuel filter
*stripped and cleaned the carb to best of my abilities
*checked the auto choke diaphragm
*checked there is a spark to the distributor
*tried a new battery
*tried spraying "easy start" down the carb and turning her over
I once got it to turn over for a few seconds after I poured a cap full of "loose" (after checking the fuel pump) fuel down the top of the carb, other than that nothing but constant recharging of my battery.
was working fine last time i used it

about to admit defeat and phone the aa but I don't like giving up - any more suggestions?
I think its got to be a carb thing.
