Does anyone have a decent dellorto diagram (DHLA) which labels what all the different adjuster screws do, etc? I've googled but cant find anything decent (in english anyway).

im using a 40 DHLA if it makes any difference, any help would be greatly appreciated!

edit: I've found this one which is a start, but id like one that tells me what all the connections are for as well.

I've read that one a few times I found it pretty good. I have a copy of Des Hammill's book on power tuning Dell'ortos and Webers. Try www.dellorto.co.uk they have blow apart diagrams of DHLA carbs.

I'd get thee a copy of `How to build and power tune Weber & Dellorto' by Des Hammill. Best tuning book for Webers too.
You can get from www.pitstop.net.au for around 40 bucks.

I've got a Dellorto factory book too, but it's a POS.
