Warm start headache

Hi everyone new member , 

I have a golf cab 1.6 automatic 1986 which is giving me issues on warm starts if I pop in a shop come out and no start it turns over fine but not starting , I have to pull choke right out and it starts somtimes maybe but horribly like it's freezing cold even though it's well warmed up already , 

Up to now I have changed the fuel pump which is on the engine block not in the fuel tank 
Also accumulator which is bolted onto block
Spark plugs and leads 
Dis cap and rotar 
Fuel filter in engine bay

I've looked in the tank and looks clean 

The car has had this fault since I bought it apart from that it's perfect , it's had a Weber carb fitted previously and all seals look ok 

Any help appreciated I will have a good go at solving this with your help 

Cheers golfers
