1968Vitesse25, You should. Had the GT6 booked in for an MOT on Saturday, took it out of the garage on Friday night for a final check. Petrol poured out of the front carb. Stripped the carb down to check the needle valve, still no joy. So cancelled MOT. Saw this thread on Saturday night and brought two on Sunday after it was confirmed that they would fit CD150s. So to all thank you for the lead. Hopefully MOT next Saturday. Graham
