I figured it was common knowledge about the existance of the 89 carbed 1.6 16 valve. I see it mentioned a lot on other forums.
Let me ask you this question - you've seen it mentioned on the internet forums, so it exists - is that about right?
I'm sitting behind the Suzuki dealer parts database application, there is no 1.6 Sidekick with a carburettor shown in that database - if you were in my position, which information source would you believe?
Let me take it one step further, the 16 valve 1.6 engines don't appear in the database prior to 92 - if you were in my position, which information source would you believe?
Do forgive me for thinking (and suggesting) that such a vehicle does not exist.
After reading your post, I did a quick google search, it didn't turn up much on 89, 1.6, 16 valve carburetted Sidekicks - I did find stuff on 89 1.3 Sidekicks with carburettors, 89 1.6 Vitaras with carburettors - both of which I know exist, and both of which have 8 valve engines.
How about you post a link or two to the other forums where there are mentioned a lot, so I can be properly educated.
