VHSB Needles & Atomisers

Would anybody have (or link too) a chart for the needles and atomisers for the VHSB 34

I cannot find any information to tell me what needles/atomisers are richer or weaker

Presumably a DP266 is leaner than a DP268 (as I know it would be with PHBH, lower being leaner)

But, which atomiser is richer DP or DQ?

And needles, what is the range of needles and in what order do they run?, there’s no logical numerical order with PHBH X needles so I don’t suppose K needles are any more obvious.

Thank you

The atomizer code relates to the physical size of the delivery tube

IE. DP 266 has a 2.66mm diamter. DP 268 2.68mm diameter (therefore richer) etc.

The DQ atomizers are taller than the DP and therefore provide a leaner mid range on a like for like needle setting.

Follow this link for the charts. http://www.thisoldtractor.com/gtbender/ ... needle.htm
