Evening all, picked up these carburettors to replace my very tired 150 cds's on my mk2 vitesse(as noted I was looking to get them reconditioned in an earlier post). I've bought them as 150cd items, but straight away I've noticed a few differences. As ever onto Google to find out what they really are (just say "CD" no numbers)but I've ended up more confused. Any ideas..150 cdsve from tr250 or tr6 seems to pop up, but I thought 175 cds came on the tr6?? (Got some of them, but need refurbing) If they turn out to be gt6 carbs and they an improvement on the 150 cds originals? ? Any help, info or pointing and laughing welcomed.
