With the current and probably on-going difficulty in sourcing atomisers for the old VHB carburettors, can anyone give an opinion as to if a 260AH atomiser will give a richer or weaker mixture than a 260U? The 260AH appears to have larger side holes than the 260U so does this equate to more air in the mix?
Not sure about these atomisers as I am an old Amal man.
