u.k. '89 240 with b230k

Why didn't you ask on Volvo Owners Club (UK) website? Try either Les Jones in Tonyrefail (on trading estate opposite Bryn Golau, Gilfach Road) or, if you go onto the old airfield trading estate near the Pied Piper, Bridgend, you should be able to find the ex GMG Ewenny team who bought out the Volvo servicing part and setup on the estate. I have a 244 with the B200E engine which is fuel injected, the parts will certainly fit your car, if that is any help.

All the best, Peter.

Can you just send the carburetor off to be rebuilt?

Thanks Peter and if I were to convert to fuel injection would I just get the head and associated parts changed or change the engine?

Been poking around today and found more rust getting in to wheel arches and another patch in floor so perhaps time to call it a day with this as I only have another 5 months mot and will need to be welded again.

So fix it. That sounds awfully like an air leak somewhere around the inlet manifold. Could be ignition timing too - particularly worn centrifugal mechanism.

Volvo built carburettor engines for years. They're not exciting, but they work, and they go on working. There's nothing magic in there, nothing that we didn't spend years sorting out without thinking twice about it. Volvos are only "hard on their carbs" because they do twice the mileage other engines do before terminal failures, so you see wear in carb parts that don't normally suffer.

Yes, the injected version is probably better. But not so much better that I'd swap engines without trying to fix the original fault first.

What's the carb model, BTW ?
