A question you the technical bods! I took my cossie for a blast as soon as I got back from holiday and whilst having a tear up the engine stuttered popped a bit then lost all power! I thought cos I was low on fuel (I was heading for the nearest shell garage at the time) it might have run lean and busted a piston or rings! I did a compression test yesterday and the readings were 70 psi, 70psi, 60psi and 80psi I haven’t had the head off yet but from these readings does taking the head off sound like a good place start or are these reading ok? It would idle but it was slightly lumpy as soon as you tried to put it under some load it would stall?
