I ran a dq267, k6 and 158 MJ for years.
Bit rich low down but was happy as i could ride through it and fine at mid and top.
Could have probably dropped to 266.
Was talking to someone at ambleside who has just spent 160£ + to rebuild a vhsb: side, liner, atomiser and needle
.
Last time i rebuilt i didnt change the liner. It made a difference but i reckon it needed a liner.
Moved to phbh, very easy to set and cheaper on parts
