Re: Carb Conv Kit, Weber Single Downdraft conversi
My vote is for the SUs. They sound better and feel better without a doubt. That being said, I currently have the DGV on my car.
The first set of SUs I rebuilt were great! They went on my mom's MG Midget and the tuning was a breeze! It's not even that difficult so long as you have a PERFECTLY MATCHED PAIR. And I'm not sure I can stress enough how important it is that they match as best as possible. I was very meticulous on the rebuild and my rebuild time paid dividends on the install and tuning.
As it turned out, I never realized that for years my dad would just grab two from the carby bin and slap'em on there. Looking back on it, we were probably trying to balance carbs with completely different needle profiles, misaligned jets, different amounts of wear, maybe even emission controlled with pre-emission carbs. It's NO WONDER we never got the cars to run smooth!
Finally I gave up and got a Weber. Its out of the box tuning and performance was much better than the jumbled mess I was used to, but once I felt what a good pair is supposed to feel like I was converted! SUs all the way.
So why would I have the DGV back on then? Well the last set I did just as meticulous of a rebuild but once it was all said and done, I had a vacuum leak at the rear carb's throttle shaft. I switched back to the DGV because it was my daily driver and even though I have replacement shafts now, I haven't had a chance to make the swap back. Add to that the fact that I'm now piecing together a fuel injection system and there ya go.
