But at what throttle opening? Spitfire's chart is a good example of why we need to do plug chops at all throttle openings. So many times I've heard lads saying "I took it out for a run, got back and whipped out the plugs, they look ok/rich/lean"  ....So what you have done is check them at tickover, coz that's the last thing the engine did, the last throttle position before you shut it off.

And if you DID do proper plug chops I'll get me coat ;D
