weber dfev 32/36 blocked

[timspider]

I have a 5 month old weber with less than 2000 miles on it. After multiple issues, it is now blocking fuel at or close to the inlet.
I pulled the filter screen and cleared some tiny debris. No change.
I'm hearing references to a needle that may be the culprit.
where is the needle? Can I get a visual on it?
Any other suggestions as to how to get this fired up?
Thanks
