DCOE Weber Carb tuning manuals

[RB30X]

I'm looking at getting a manual on weber carbs and I've come across these two:

 

http://cgi.ebay.com.au/How-to-Build-and-Power-Tune-Weber-and-Dellorto-DCOE-and_W0QQitemZ350285211324QQcmdZViewItemQQptZAU_Non_Fiction_Books_2?hash=item518ea026bc

 

and

 

http://cgi.ebay.com.au/Weber-38-48-DCOE-Carburettor-Tuning-and-Service-Manual_W0QQitemZ360212168742QQcmdZViewItemQQptZAU_Clothing_Merchandise_Media?hash=item53de518026

 

Can any of you give some feedback on these or recommend a better book. The first one mentions power tuning which is benifitial but I'm afraid it might be generalised as it covers side draft and down draft, weber and dellorto, where as the second one looks purely on DCOE weber carbs.

 

Thanks for your help.

I'll be thinkin that a few of the blokes here have the first one (like me) but the second one looks like it would be the go..

I use this one by HP Books and find it very good.

I've got the des hammil one (first link). The dhla and dcoe carbs are really silimar, so the processes described don't really change too much.

 

I don't think that there would be much difference between the two books to be honest.
