Hi, thought I'd like to share with you guys a lil something about weber carbs on a 4g13/5 engine. Just an experience from my previous setup during my old weber days. Miss them 'sometimes'.
This is a progressive downdraft carb, with one barrel opening after another. Never had the chance to use it, since I sold it first. Skywalker from SIC had the experience using it, while I only had the experience on purchasing it and making some money out of it. Here's some pics.
Now, this was my first downdraft weber carb planted on my engine bay. Got it full set with manifold, custom adaptor and K&N airfilter. It's a double barrel carbs opening at the same time. Nice. Lovely sound. Good throttle response. FC is more or less the same with the OEM aisan carb.
Used it for about a month or two, then it's time for upgrades, to a better and nastier carbie. Yeah!!

4 Barrel opening at the same time, well, what more could you ask! Have to throw a mild cam just to match the power produced from this mean devil at the tiny 4g13/5. engine. Getting the right tuning and setup is not easy, but not impossible. Once you got it right, it's an addicted habit to smack that acceleration pedal. Managed to get 0-100 at 9 secs.
After all of these, i've changed to a modified standard carbie. Ehem.
Conclusions: Carbs really do make wonders!
