DDK - Die Deutschen Klassiker

As can be seen from the following short video, once I get my engine started it will idle at nice low revs:

However the car is very reluctant to start and will only fire up with the help of easy start spray. I charged the battery fully and the engine turns at a reasonable good speed during the starting process. I suspect it's fuel related. I put 4 gallons of super unleaded in when Mike and myself first started the car so I thing there is enough fuel in the tank but as you can see from the video below the fuel filter doesn't seem to have a great deal of fuel in it and fuel is entering in a trickle. What do you think?

Is the tank screen clogged?

What is your method of starting ? and how fresh us the fuel ?
Do you have the hand throttle still ?
With fresh fuel, several pumps on the throttle, to pump in fresh fuel, crank with lots of throttle opening ( full? ) and as soon as it catches, let it sit a while on a healthy level of hand throttle until warmed through ?
I think until the air is bled out, the filter will always look full of air. Can you bleed the air out, or prime the filter.
Or switch to EFI !!

Almost certainly a form of fuel starvation from what l've seen in vids
