I know a mate who had problems with his Honda engined Rover called a mobile mechanic out, as he was having trouble starting it.

The cause of the problem was sticking valves, not closing properly. Think it was the engine with 4 valves per cylinder

So mechanic stuck in a bottle of industrial strength Redex or similar to clean & lube the top end. Did work too.

Normal Redex isn't as strong, but I can't see it doing any harm
