Well,
I rebuilt my 2be carb about 3 months ago. Mine was running like dat b4 i rebuilt it tho.
Are all d vaccum hoses in the right place?? Did u check for any damaged jets wen u rebuilt it?? 
Also wen i rebuilt mine i had to reset the fuel/air mixture using the adjustment screw on the side.

Also wen i rebuilt mine i had to reset the fuel/air mixture using the adjustment screw on the side.vacuum hoses are correct , i cheked this on the diagram. Didnt check the fuel/air ratio yet , gonna check that tonight. I contacted a store for a weber but they are charging 425 euro (360 pounds) for it . So i hope i will get the pierburg fixed...
is lever that connects to the little nylon lever arm, right on top of the carb, the right way round? Sometimes this lever can rotate in the wrong direction or something like that. Sorry I can't be any clearer as it's so long since I had one.
I believe this is wat toby is talking about.toby wrote:is lever that connects to the little nylon lever arm, right on top of the carb, the right way round? Sometimes this lever can rotate in the wrong direction or something like that. Sorry I can't be any clearer as it's so long since I had one.
And the selenoid that controls it.
Make sure the selenoid is rotateing the lever the right way.
Make sure u did't hook it up backwards when u rebuilt it.
well , that works correct . Tough , I had problems with that a couple off months ago ,the metal between the electromotor and nylon lever arm kept falling off. Had to put it back every time i wanted to start. Also the temp sensor on the intake , wich is responsible for the position of the elctromotor failed. But the choke is working correctly now. I think It's the big grey thing on the other side of the carb wich regulates the idle that is broken , but my knowledge of this carb isnt just good enough.
So i am hesistating , should a go to the bmw dealer to let it fix , or should i buy the weber conversion kit ? I think i am gonna go for the weber , becoz it will be a new one.

The Pierburg, as fitted to E30's is a lost cause, or at least the control system connected to it is.
IIRC, with a little ingenuity, the idle control mechanism can be removed completely, and an old fashioned idle stop screw fitted instead. It's a long time since I've seen one of these, but I seem to remember there's a casting on the carb where a screw would have been fitted in the original design.
Mixture screws on the carb will still need setting up, though.
Where are you? There are second hand Webers available on the zone from time to time, and there shouldn't be any problem with a second hand one, as they are usually only a fraction of the age of the cars they have been removed from. You can buy a lot of postage and packing for 425 euros!

Shouldn't be any great expense shipping to Antwerp from the UK. Ask in 'parts wanted'.

Wat about the pressure switch on the idle control mechanism that controls the electric valve for the distributor?? If u removed the idle control mechanisim can u bypass the electric valve and run the vaccum hose straight to the inlet mani??

That's how it was done for decades before all the electronic gizmos arrived on the scene.E30-830 wrote:can u bypass the electric valve and run the vaccum hose straight to the inlet mani??
I suspect most of the extra stuff is for emissions control, rather than any advantage to the consumer!
