I have a 1981 Volvo 242 with fuel injected B21 engine. We have rebuilt the engine, but now find fuel injection to be faulty and parts are not available. I have heard that there is a conversion to a carburator intake manifold and carb. The person I talked to thought that either someone makes the manifold or that there are instructions to modify the stock intake manifold. Another person thought that a Volvo Penta marine engine carb manifold might also work, but I can not identify the part number. Does anyone have experience doing this conversion?

You should be able to get Bosch K-Jet injection parts for your B21F. www.k-jet.org is a good source of info and advice. The Canadian B21A had a single SU HIF6 or a Stromberg 175CD2SE carb. You could make the change with Canadian parts but the K-Jet should be the more efficient system.

I agree that KJet [may be Lambda?] is a great system and generally the only problem to stop it working perfectly is tiny little filters on distributor and espec on WUR
