Is it old fuel?
Have you a filter or is it open mouth? (blocked filter)
Is the choke fully closing?
Give carb' a good clean.

Just some things to think about or to do....

The fuel is old,and just put fresh in,flip choke so it shud be ok?,not open mouth,but has a cheap fancy chrome filter,k/n copy

Try without the filter on.

I think the atomiser you have there is for a Phbl carb. Do you not need the Av268 atomiser ? Good luck with it.

I would Defo try it without a filter, and also give the filter a good clean.

Still the same without the filter,got myself a 46 pilot jet to try,the carb is a PHBL DELLORTO, is the AQ Type the correct one for that carb.Thanks for your help
