Pieburg carb replacement.

[grumpygramps]

Hi from a total novice.

Last year we picked up a 1987 T25 with 1900 cc engine and auto gearbox. Av fuel consumption on long runs between 22 - 25 mpg. The auto choke has been difficult on occasion, and it has been suggested that we replace the Pieburg carb with a Weber conversion kit.

Is the combined cost of the kit and fitting of around £600 justified by improved fuel consumtpion and performance?

Any advice would be appreciated.

No. Lots on here about this. Use the search feature. I'd simply be repeating what has been said numerous times in the past. Neither is a 009 distributor a code word for 007 - it is unsuited to the engine. Engines need to breath both ends to get any noticeable power increase and even then, economy is unlikely to be a bi-product .

webbers are not suited to these engines and fuel systems.
dont waste your money trying, as has been said, do a search,
there are soooooo many webber wont run right, cant run threads on here it is obviously a bad move.

Better by far to clean, regasket carb and replace choke with a known good secondhand one. Theres also Roger Ball in Clacton if you find the throttle shaft has play in it and causing poor idling. Webbers can work but there are far more cases where they don't and over 25 years I've seen numerous webbers with running problems. They generally lack the vacuum takeoffs or just don't suit the power curve at all. Lot of hassle for nothing but trouble.

As said = service the carb = all will then be as good as it can be in that respect and lots cheaper than a sh1tty Webber.

Now, if you want economy with no loss in performance, add £300 to your £600 and get it converted to LPG as MANY on here have done. It equates to a saving of over 1/3rd in fuel costs, therefore equivalent to up to 35 MPG with no noticeable difference in performance = win win

It pays for itself in no time if you use the van fairly often. Ours was paid for after around 9 months of fitting the LPG. Click here http://www.gasure.co.uk/4steve.html" onclick="window.open(this.href);return false; to use the Gasure "how long before I am in profit" calculator"

Oh, by the way, many, including me, find their vans run smoother all round on LPG

Av fuel consumption on long runs between 22 - 25 mpg.

that's about spot on

Webber conversion wont give you more mpg..
As suggested, add a few extra quid to the cost of a webber and lpg it...

Yep.. if you are getting 25 out of an auto camper then your doing well.. I'd suggest leaving well alone apart from prpper servicing and making sure tye pressures are right..

My thanks to Forum readers for the help and advice regarding the Pieburg.

It was much appreciated.

The carb is being refurbished so hopefully the starting problem will be resolved.

If you still have problems, feel free to come back and ask.

Hi. Further help required as the Pieburg saga continues.

I managed to disconnnect the hoses and electrics, but couldn't work out how to remove the carb from the manifold.

I removed the upper half containing the butterfly. When I looked at the throttle linkage, it seems to be held together by a small pin with a circlip at either end. Is this the way to disconnect the link to the carb main body?

I can't see how the main body is fitted to the manifold. There don't appear to be any bolts underneath.

Do I remove the manifold section as well?

Are you absolutely SURE you should be doing this job ? Do you have a manual ?

Well.. the Hayens manual would show it..

But if you have remove the top of the carb then you have undone the 3 M6 nuts which hold the carb to the manifold.. so I suggest you give the body a tug as its stuck to the manifold... you doo need to undo the 2 10mm bolts holding the throttle cable pivot bracket to the manifold too..
