engine and drivetrain Needed: Recommendation For Buying Carbs/manafold

[Healingwriter]

I own a 1971 2002.  I've decided to convert the one barrel carb to a two barrel.  Is Weber carbs. the best choice?

Can someone recommend a website for purchase?

Thank you.

Yes, the 2bbl Weber is a huge upgrade and improvement.  However you probably have the stock single barrel intake manifold.  So the conversion requires the right kit.  You need the intake manifold as well as the carb.  Study the website and understand what you need.  It is not a matter of buying the kit with spacers if you are going to a 2bbl.

 

We just did the job on my '73.  There were a few problems:  Some of the manifold openings were poorly threaded and needed to be chased, some parts of the manifold had to be ground in order to clear the socket, and we needed to build up one gasket to get it sweet to the head.  Nothing major, but having the right tools and comfort with the job is required.  Start of tear down to starting the car covered 6 hours.  Dialing it in from there is the trick.

 

One tip.  We heated and bent the existing throttle linkage rather than re-configure the included parts. 

 

We used the electric choke.  You remove the included water manifold and replace with electric if that is your choice (much cleaner/easier).  Power came from the coil terminal.  Many will scream at that.  We also elected to swap the water jacket cover, made a gasket, and keep the heated carb arrangement in the belief that heat is a good in winter.  We needed washers so that the cap screws did not bottom out.  Owner's preference. 

 

We installed the Weber 32/38 DGEV.  It is a progressive carb and opens the second bbl as needed.  Stab it in the midrange and you get a rush of power akin to the kick-down of an automatic.  Your throttle becomes the smile maker peddle versus the Solex 1bbl.

webercarbsdirect.com is where I bought the WK204 kit for the 32/36.  The picture doesn't show the manifold, so I'd suggest you call.  I said it was 32/38, my bad.  You need the kit if you are replacing your stock 1 bbl. 

A motor is an air pump.  The carb and manifold more than doubles the air intake.

 

Good luck

Here is the manifold. Weber direct was cheaper. Best

Do NOT buy from webercarbsdirect.com if you want real weber parts.  Any real made-in-spain weber in North America is being distributed through Redline (which is where Korman, Ireland Eng, Metric Mech., Pierce, Canon etc. source their carbs).  Most of the time if you order a downdraft setup through a 2002-specialist they will jet the carb as close as they can to your setup, they do cost a bit more up front, but your not paying for a bunch of extra hardware.  

 

Interestingly they (WCD) have the legal right to call their carbs "webers" but are not affiliated in anyway to the Weber we know.  http://genuineweber.blogspot.com/

 

The Cannon manifold shown above was originally designed for the smaller 1600 head ports and will need to be ported to run optimally (fun time with a dremel and intake gasket).  The upside to the Cannon manifold is that you can run the taller version of the downdraft air cleaner.  It is often cheaper to find a 2 barrel manifold from a later 2002, inlarge the carb port, and call it good.

Utt oh.  I may not have bought the carb from them...now I have to find the charge.  It is a Redline kit for sure, made in Spain, kit K202 for BMW.  The old carb is in its box.  The used manifolds which need hogging were $250 plus shipping.  The point is you need the 2 bbl manifold and not the riser kit.  Carbs Unlimited, $432.00 shipped is what PayPal shows.  Washington State.  Seems right.  http://www.carburetion.com/
