Dean,

The Webers distributed by Redline from Spain had major modifications to them to make them easier to tune and make them more streetable. I would call Redline and review the differences for tuning. The person who tuned my carbs were unaware of the changes and it lead into a whole learning process, as he was used to working on the Italian original models. Nothing that could not be easily adjusted for, but it was different and what he had to do was unique from the Italian models. When talking to Redline, they will tell you if they tuner is used to the Italian models without referring to the handbook or calling, the tuner will goof it up (as mine was, and wad a little embarrassed he did not know about the difference).

Point is, there must be a good difference. The guys at Redline are very knowledgeable.
