peirburg carb on mk2 1L polo

pierburg carb **** up. No idea what is wrong with carb, but got another off a scrapper and it runs better than it did before.



it seemed to be flooding the engine, and spraying it all up and out top of carb all at the same time.



I am no expert on carbs, but I have it out on my bed and wondering if I can fix it again. I suspect(guessing) that the float has failed and sunk. Anyone agree lol, I have the pic breakdown of parts from hbol to go on.


I think they are the Same carb as a Nova and a Skoda Favorit (either Pierburg or Jikov licensed copy. Same carb though).

Don't know if this helps you at all.

If the float has failed and sunk it will have petrol inside it which you will hear sloshing about when you shake it. On your bed you say? If you're doing this stuff indoors I hope you've got a fire extinguisher handy, not to mention some good insurance.

Steve

does it run at all? I would first check cam timing, then ign timing

They all do that.

You won't find a good Peirburg on a scrapper, either.

The only way to fix it is to send it away to a carb. specialist to be refurbished. It's not cheap, though.

Alternatively, try and find a compatible Weber and manifold.

it dont help, but yes lol, i thourgt it was same as a fav, used to have a fav a few years ago.

never had issue with any fav carb incidently, but polo is now on its 3rd.

Webcon used to do the direct replacement kits to suit the original manifold. Not performance but "reliability" upgrade.

I empted n shook n waved lol, n left outside for a few days haha. will look at getting to float n will submerge into a glass of unleaded. outside of couse :-)

incase u missed that bit :-) above. it wud not start let alone run till i changed carb.

so have you checked the cam timing and the ign timing?

Silly question, but is the carb base warped? Warped base, made airleak, no way idling, but might run with throttle, or just flood.

Carburettors do not just suddenly die and become completely unusable. Tell us the whole true story.

Oh, they do.

Happened to the Pierberg on my Golf.

They do if it's a Pierburg. (or a VV, or a Varajet for that matter)

Tim..

In news: snipped-for-privacy@bt.com, Tim (remove obvious) wittered on forthwith;

The Pierburg on the Scirocco I'm selling (check out my ebay spam elsewhere) works fine, and that's been repaired!. Admittedly the previous keeper is someone who used to run the parts department in a VW main agent.

For once I agree with Steve Peirburg are pretty dire IME on both VW and BMW you could transplant the injection from a slightly later polo as they are the same basic engines. but it is quite a bit of fuss.

unless there are bits broken off it will still run reasonably though. Carbs are very simple devices, the trick bits are all added on to give refinement, the basic device is just that: basic , there is little to go wrong, go out of adjustment/wear, yes. My point is that they don't just suddenly stop working completely, even a flooding carb will work to some extent, even if it runs terribly.

There has always been an element of 'I don't know what's wrong, it must be the carb.' I used to see this a lot when carbs were current, especially the dim AA mechanics, 'it needs a new carb' 'we'll trailer it 200 miles back for you' it actually needed a rotor arm, pretty basic stuff really.

I did this with a Mk2 Polo with poor Pierberg carb and awful auto choke. I couldn't find a manual choke conversion kit for it so bought a Weber carb from German & Swedish complete with manual choke. Car ran perfectly after that.

Alan.

Seconded/thirded/whatever. The Weber carbs for the Polo generally last the life of the car and are in a different class altogether from the Pierburg/Solex/PIC s**te they also used.

Solex were great. Well mine was. Used more oil than the engine did, mind. :-)
