How can I get my Robin NB211 to start ?

Thanks for your help. However to elaborate further, I took the filter off the fuel pipe to see if it made any difference just for testing purposes but it didn't. Anyway I subsequently thought that if the fuel bubble was able to pump fuel up to overflow it must be ok. Also took carb apart and separated all sections but nothing obvious. Gaskets all seemed ok so reassembled and still no joy; a bit of a puzzler.

No is the simple answer, this is just a breather to stop a vacume building up in the tank, it is nmore likley a blocked fuel filter in the tank, or a cracked broken fuel hose, failing that it is a blockage in the carb
