Hello all, Just rebuilt the head on my new project (mk1 gt6) Fitted 6 3 1 extracter / honed refabbed manifold etc / HS6's fitted and all bolted up and checked. This is all on my new gitfire project, not my main mk1. I am in the dark on what needles/jets to fit now. The carbs are missing their id tags but they are ex Dolomite sprint units and rebuilt. The su spec catalogue has led me too BCY needles(standard) & AUD9105/6 jets but I would really like to seek some more advise here as the existing Dolly needles are a far richer profile. plus the fact that I'm using an extracter manifold and kn's too. I like to work things out myself and usually do, but I'm raising the help flag here. Again this is all on my latest project, so I'm avoiding the temptation to pop it all on my original mk1 gt6 and remain ready to get on with the mk3 spit shell (that it came with) and ready it all for a bit of summertime fun. So, any help would be greatly appreciated. Thanks a lot, Andy.
