This actually happened months ago, but only had a chance to look into it now.
My '91 Panda 4x4 was running a bit poorly then it stalled and wouldn't start. It was getting fuel, it had a spark, and and was turning over well - so I was confused.
At last I had a chance to look at it today and so I started with a compression test. All the cylinders were around 20 to 30 psi. After a google, I thought it was maybe fuel washed. So I added a little engine oil to each cylinder and disconnected the fuel. Compression remains low, maybe 5psi more with the oil. Surely oil would have revived the compression a little more?
Any ideas what is wrong? The engine has been idling poorly for sometime so I quite often run with a little choke to stop stalling at lights is town. Could I have flooded, fuel washed the cylinders and worn out the piston rings? On all 4 cylinders???
I'm also thinking the carb might be at fault for the not starting and may need a service, but that doesn't help the compression problem.
