SU carb question

[Zedyone_kenobi]

I recently purchased a book on how to tune and rebuild SU's as good light reading, and I ran into a problem. It covers all manner of SU carbs. HS, HD, HS2, HS8. I am pretty sure I do not have the later, but after I get my carbs back from Z therapy, I would like to know which chapters to follow. I have a stock 71 240Z. It has an E46 manifold for what its worth.

Are you sure those aren't the original British SU carbs? Our carbs were manufactured under license by Hitachi.

Those H series carbs are in fact designations for the SU SU's. Our Hitachi carbs are equivalent of the HS series. HS6 is the comparable to the 46mm Z and 2liter roadster carbs.

With your order will come the JUST SU's DVD which I can guarantee will tell you more than you ever wanted to know about these carbs.

I will testify that his statement is accurate, at least in my case.

But I finally understand how they operate, which had been a mystery to me for decades.
