Default Free JD jetting spreadsheet

A while ago I found this http://home.att.net/~wbarrow/jd/jd_index.html

with links to a 2002 demo version of the JD jetting database.

For anyone who has not used this it is immensely useful to see where the different carb parts - jets, needle taper and clip position etc all effect the fuelling.

I'm not sure if this is actually a demo or not - I couldn't find anything to indicate it was but maybe the full version has more stuff?

Anyway I would recommend having a look at it and if you think it's useful buy the latest version which will have a couple more features plus more needles to select from.

He has a brand new one available that covers many more needles. If your into tuning your carb it's $20 well spent.
