rough idle very smoky

[blinkyeatu]

i found the shaft wasnt pulled up fully so did that and its sounding better i had another look and i can see little air bubble in the inlet bit so guess airs still getting it somewhere. my thoughts are the gasket on the head of the pump i didnt change that :/ also the o rings on the shaft but as there isnt any fuel spewing up through i thought it shouldnt be that and theres none around the gasket

ooh also it mainly puffs when i accelerate.
im hoping its all just air causing my problems
