Hi,
I originaly started this thread back in November when I was contemplating replacing my up-draft Zenith with an SU. After taking advice from this forum, and also finding some needle info on the old forum, I have just completed the job.
I'm just posting this now to thank those who offered their advice, and also to state what bits I ended up using incase anyone else is searching for the same information.
I managed to buy an SU 1 inch OM type carb on ebay. I know these are quite difficult to come by, but it was worth seeking one out as it made a nice neat compact installation with no flange adaptors etc. I used a standard late side-draught type combined inlet/ exhaust manifold, and an AN needle. (I tried a couple of other needles but the AN gave the best pick-up and mid-range acceleration). I've road tested the car with a full scuttle tank and no pump, but I plan to fit a Moggy Minor type LP SU pump.
So thanks again folks for all your advice. This forum really is a great asset to 7 owners.
