Reading a technical write up on a US site 'tother day and came across the reference: "beware DPOs".
Wondered what this was, as I'd never heard of this before. Turns out to be a reference to "Dickhead Previous Owners" - the ones that superglue sparkplugs in when the threads are shot, don't change the oils for years, don't lubricate things, make a dogs dinner of your wiring harness... you get the idea!
So - technical tip - watch out for DPOs!!!
