weber carbs work great for daily driving, with very little maintinence
any difference between the 45 and 48 as a daily driver, And as for the choke, couldnt you just keep your foot on the gas for a few mins as the engine warms up? I am in southern california so cold weather would not be a problem. As for instalation? Pulling the old carb and Removing the rats nest, would it be to difficult to install myself, without any problems

it has to be jetted accordingly. or you can do that too. i never had a problem starting a 48 ida in my street port during 50'ish degrees here in LA. Yeah, thats cold for me. brad, here's what you do...you buy it from 680. if you wanna install it, drive up from SF valley to my hood and I will help ya. Just bring the carniceria and heine...

Everyone else here speaks their mind so feel free... 
Really, the only carb that would have any sort of "issue" is the down-draught IDA because it doesn't have a choke. But, that's only in really cold climates. I had one on a 12A extend-port for almost two years and it never once failed to start with the first turn of the key when cold. It did have a slight hot-start issue due to heat soak but that was solved by putting some phenolic spacers in.

I think Ill be getting it in the next few months, also once everything is off how hard is it to put eveything back on. All the stock components? I still have to smog it every two years. and its been a year so I have to smog it next september. Just wondering how much work I will be in for.
that depends on the driver... I prefer IDA even on street cars due to its aggressive response. As far as the blow-thru system, I dont know but I will be experimenting with blow-thru in the RX-3 using 44 mikuni for now (it seem I will be calling Rob too to get a 45 webber since I dropped the mikuni last night and cracked the body) once, im familiar with it, then I will try the downdraft carbs such as IDA or holley.

i mean that whistle sound happens when its idling low.. and i put gas on it.. to try and up idle..
but it does that weird whistling sound and goes back to low rpm.. and i put it on D.. it dies..
i only reaslised it tonight..
and it only happens wheni start the car warm.. like i start it.. leave it for 5 -10 mins.. then try to start it.. and it struggles..
just like the nikki before it

I have been using Weber DCOEs for some 40 years on different cars. Once set-up they make a good daily driver and a weekend hotrod out of one car. I used them very successfully on a whole series of Ford powered Lotus cars when money was no object. You just could not buy a better carb. Since efi came in there has been lttle development of carbs, apart from what Sterling and Carl are doing to the Nikki. Thus Weber is still the best stock carb.
The inlet is the crucial part, they generally need to be long to widen the powerband. I once set-up one in a Mini Cooper S where we ended up moving the speedo nearer to the steering wheel so the trumpets could come into the passenger compartment. On a throttleback they shot flames between the seats. Not a good daily driver!
But seriously, I do not think you can go past a Weber, especially if the price is right.

I have the 45mm webers and racing beat intake manifold on my 13b in my 84. The weber carbs are great, the only downside is starting the car up in cold weather. You'll have to wait a bit for the car to warm up before you can go tearing up teh streets, but you should be doing that with any carbed car anyway. They make a good street and drag carb, you get the gid-up when you need it.
I had two Dual Dellorto 40mm Sidedraft Carbs on a TWM Intake Manifold on my 85 GSL. The thing screamed. I had no problems starting, only about 3 to 4 pumps on the gas pedal and the thing started right up. I ate gas a lot more though, which is something I regreted, but the power gain, on my stock 12a was increadible. If you cruious I can send pics of my car, which I no longer have, but I am working on my second project, which I will be putting 2 Dual Dellorto 48mm's.

I was looking at the weber dcoe intake kits on rotaryshack and was wondering, is there a place on the manifold to run the vacuum for the brakes? Could I possibly just drill a whole and put a plug in it so I could run the line for the brake booster?
