Good Bye Pierburg, Hello Weber!

Conversion Weber 32/34
My Golf came equipped as standard with a Pierburg 2E2 carburetor. When this one works fine, it's a great ride...

But in the other hand, when it starts acting, it's a PITA : it's full of vacuum modules, dilatation elements,wax component, in which the cooling liquid goes through... Kind of a Rube-Goldberg machine, next to impossible to fix.

And you guessed it, mine started acting weird, it did not like last April's engine swap (I did write about it at the time already).

Around a decade ago, I had found on eBay Germany a rebuilt 2E2 for a fair price, but unfortunately the vendor doesn't exist any longer. There's a specialist in the UK (Bromyard) that offers complete Pierburg 2E2 rebuilding services, but for a hefty 395 £ + S&H (that's over 500 €), I wasn't too keen on going again with that same Hell-of-a-carb (that being said, looks like that company does a great job).
I also had the option of buying a brand spanking new Chinese reproduction of the Pierburg 2E2 : you can find them on AliExpress, and they will set you back around 100 €. I have to admit, I'm a bit skeptical on the quality of these...

Long story short, I finally bought a Weber DMTL 32/34 conversion kit from EuroCarb via eBay. It's cheaper this way than from national french re-sellers, 324.50 £ w/ S&H (which is 380 €, would have been 455 € w/o S&H at local stores).

It's a beautiful kit, very well engineered. Installation instructions are clear, it's almost plug'n'play... Even thought the french traduction is a bit sketchy (and the fuel line clamps are a bit small, but I'm nit-picking). icone smiley wink
So now, no more faulty automatic choke, which functioning is a matter of voodoo sorcery, back to basics with a good'ol manual choke!

Installation note : the small bit at the end of the throttle cable cameinto contact with the vaccum element at the back of the carb, preventing the throttle from coming back to idle. I snapped it with a pair of pliers : fixed (on the middle picture below, you can still see the contact point before the modification).

I installed the bloody thing on 01/29/2017 and since then : pure HAPPINESS! Starts neatly, acceleration is linear, the engine doesn't die on me any more when cold, more torque at low revs... I definitely should have done this a long time ago! icone smiley laugh
