I have recently purchased an XK120 OTS and notice that it is fitted with W02 needles, (H type Thermo SU's). The information I have found suggests that these are for cars with remote air filters. I have pancake filters and again information suggests the requirement is for RF needles.
What I can't find and hoping someone knows is how much difference is there between the W02 and RF needles. The engine runs well but is definitely running slightly rich.... although this may be more down to my inexperience in tuning (just getting to grips with colourtune).
If anyone can suggest that these needles are "wildly different" or "pretty much the same" I would appreciate.

Burlen publish a small booklet with needle dimensions.
From that book:-
RF .100, .095,.090,.0863,.0802,.0768,.0732,.070,.0665,.0630,.060.,.057,.054,.051
So your WO2 is a weaker needle all the way from station 3 to 14, by quite a bit as the stages go up.
