The tinternet is your friend here for a starting point at least but I would take all info with a pinch of salt as no two engine set ups are the same due to carbs,cams,head,exhaust manifold etc.
This is what a 10 second search on Google came up with.

Session on rolling road with someone who knows what they are up too will pay dividends in the long run,used to work for Weber supplier and tuner in the 70's and its not an exact science as Phil posted above.
Good check on all the bits and pieces inside or overhaul may also be a good idea and again save bother later.

Thanks Phil and Flyerncle,
I did a search but phil's one's didn't come up, must use google more often.
The carbs have not been use for over ten years and theres a couple of bits missing.
I have stripped them down and about to clean them up today.
Once i've got my fuel tank and the electrics sort i will get a session on a rolling road booked.
Thanks guys
