"Blow" is kinda vague, but it sure can get badly damaged.
badly - schlecht.
The prefix for "led badly" is "mis-", so it would be "misled badly."
Absolutely, a badly timed engine can run like a heap of S--t
Certainly. Timing is critical to an engines operation and a stretched chain wont allow the valves to open and close at the correct time or the ignition to deliver a spark at the right moment.
if a gas fire has been incorrectly fitted and cannot draw enough oxygen from the area it is heating. Carbonmonoxide is produced which is colorless and odourless gas and is hazardous for animals . if it is breathed,it stops the circulation of blood. The person who breathed carbonmonoxide would die eventually.
They where treated badly and died from diseases.
They are very small creatures so it is easy for them to get badly injured or killed
Since the compression is good I would not expect it to be a burnt valve. It could be timing if the timing chain has excess play. I would also check the ignition module and the engine control module. We had a 1986 Chevy Celebrity that had an ignition problem that cause it to run badly and backfire. The service engine soon light was blinking but not posting a code. We changed the engine control module and it fixed the problem.
its having its period
Its either timing or fuel intake problem.
Not really enough information given - however - if they are badly out of adjustment you might be referring to the sound of the valves tapping - OR - you are hearing the noise of pre-ignition - perhaps the timing of the engine is off badly.
