Hi Martin ,thing is with the engine i have, the air filter has been left off it for years and looks like it has been open to the rain so the k jetronic is in a sorry old state and will need rebuilding or replacing, the oil looks to have water in it,haven't had chance to give it a compresion test yet, i was thinking i could replaced it with a volvo engine it would give me time to rebuild this engine, it really wants to have the original engine in at some time, what do you think?
