Well as we have difference of opinions on the carb thing, I did do the TFI upgrade which was extremely nice.
In my opinion, I would not put a Carter on any vehicle ever again. As a matter of fact, I am worried that just having the old Carter in my garage is going to affect the way my Jeep runs, since it is so close, I figure the Carter will f#@k up my Jeep through Osmosis. Wouldn't be surprised.
I have never heard anyone complain about a Weber (except maybe price), until now. You know they sell a kit to use your original air filter and filter housing on a Weber K-551, maybe that will solve your filter issue.
I personally, like the filter set-up.
Anyhow, I think the bottom line we have all come to is that you need to focuse on your carb.
I would do the TFI upgrade also, it can not hurt in the long run, and you will see a noticeable difference.
