Not sure about twins, but with a single HS6 on a GR manifold, an OA6 needle and red spring worked for me. This was on the 1412 stroker, dyno figures are in my sig below. These needles are also used on a Healey 3000, so do work with multiple carbs. [edit] Vizard's yellow book says for full race 1275 only, use red springs and RR needles. |
