" Are you not aware that they need lube???"
I am now!
I think they run pretty well. No discernible coughing, sputtering, hesitation. I can't remember what needle I run, maybe KW.
I do run them fairly lean with the jets set about .08" below the bridge, tweaked maybe one or two flats depending on how it's running given temperature and/or humidity. I have EGT sensors for both the front and rear carbs and try to keep EGT readings at about 1,350 degrees F. I'll go richer or leaner and for better balance depending on EGT temps. I mostly run in the 3,500 to 6,500 rpm range.
Here's a link to a video from last fall (Lime Rock Park) and you can hear how it sounds. Sadly, I broke the crankshaft later that same weekend and I'm not sure if I will have anything better than a parade lap engine (if that!) for the upcoming season. (I do have a spare Volvo B16 engine, but it hasn't occurred to me yet to try to drop that one in!)
