Hello All, I've been given a Copen. I thought this was a good thing until it wouldn't start, despite running fine the day before. It sounded like very low compression, so out with the compression tester. Cylinders 1 & 4 were showing 60 psi yet 2 & 3 were both reading 150 psi. Squirt of oil down 1 & 4, wait, attempt to start, runs. Take it for a blast, fine. Not one hiccup nor misfire. Back home, switch off, re-starts fine. Next day, won't start! Constructive advice welcomed and apologies if this is a part of Copen ownership known to everyone, but this is my first (but hopefully not my last) experience of these modern MG Midgets.
Welcome to Copenworld! My kind of obvious diagnosis woul be piston rings Have never heard of a problem like this before What kind of engine is it, the turbo one? How old, mileage, service history?
