cob, very simple trick is to dribbled water over exhaust primary pipes to find out what cylinders are missing, or not firing due to lack of compression etc.
Or a can of crc or watever you can drip on exhaust to see what is not hot! or just use your hand of your game enough.
P.S. I take no responsibility if your burn or blow urself up because you poured fuel on exhaust or burnt your hand from touching it![]()
