Fuel question

Hi there people

 

I need a bit of help or advice. I have just fitted a new carburettor kit onto my vespa 50, this one in fact...

But there doesnt seemt to be enough fuel getting to the piston for the spark to ignite. I have great compression, the timing is correct and a great spark. Does anyone know if this carb set up needs any extra settings? or could anything else be effecting the flow of fuel. Even though it is new i have taken it apart and cleaned it very carefully.

 

No blockages.

 

Cheers

Matt
