Webcon weber carb conversion?

Ross Slaughter · Mar 26th, 2021, 10:28

Hi guys, decided this is the way forward for me now.
Does anyone here have pictures of a successful install in their 740? Also where fid you put the choke lever on the dash and do you have any pictures of that?

Thanks all.

On my 1986 740 GLE with B230K engine.

The choke was fitted on the left hand side between the switches from memory on the angled black part of the trim.

No pictures as car scrapped/PX in 2007.

We had the weber kit fitted. Ran well for a few years, but jets used to block up even with 2 inline fuel filters. Blow them out and would then run fine. Eventually got worse after 5-6 years and stalling, running rough and eventually PX for a new Corolla in France, as needed a dependable car as lived in rural Normandy. Waited 2 weeks for new Corolla and in that time the 740, "Rodger" Ran perfect! Not sure what the issue was. D795 RJW. Vowed to not have another Carb Volvo. Had 240 GLT. Now 940LPT.

I have no experience on petrol volvo's but have fitted a couple of webers now. If there is another more efficient alternative i would go for it.

They are awful on fuel and the new Spanish made units are prone to leaks and poor machine work apparently. I had no leaks but despite using my gas analyzer and timing gun never got good results or smooth power curve. I tried and tried but gave up in the end. Compare that to say a su carb and there is alot better efficiency and power curves to be had.

Just my 2p

The Webcon looks designed to be a factory style replacement for the Pierburg, I can not imagine a better alternative to be honest.

It might be worth looking in to Dellorto DHLA carburettoes too, they offer a better range of jet sizes too IIRC. I was looking at them for my 360 before selling it and my mk2 golf about 6 years ago but money was tight so I went for a used weber and a service kit on that.

I think he's looking for a standard conversion Luke, rather than a performance one. Likely to be a 32/36 DGV sequential twin-choke which should give good economy and low-end torque but also good performance once both barrels are opened up.

The Del'Lorto DHLA would be great if he was adding a wild cam and 4 branch exhaust and system but not much help on an othewise standard engine, ditto for the Weber DCOE which is very different to the Webcon conversion kit. That would be something like :

Difficult to tell exactly what carb is used but a basic twin-choke cooking carb from the look.
