I wished I had learned from dad who used to do so with a loupe. No loupe needed to tell that this one could benefit from indexing. Now we can argue on whether that gap should be towards the intake, the center of the combustion chamber, the squish, or the exhaust.:d

Fair. . .

I have a friend who tried them Slim.... But I'm afraid that your male pattern baldness won't be cured by plugs..... You might want to start saving up for a nice rug though... :D

I got it caught in an elevator door when I was seven. It didn't really hurt until we got between floors. . .

Had a 1987 Chevy Pickup with a 305cid V-8. A year after having the coolant freeze, I noticed that 7 plugs were grey-black, and one was a bit "greenish". That pretty well told me I'd probably cracked the head. I'd heard they were somewhat fragile when it came to freezing.

Never pulled the head, though.

Man this business of hitting middle age is a bummer, only just forty and he's already reminiscing about long gone practices. I haven't felt the need to run a plug chop since nineteen eighty three.

Two lever carbs?
Beaded edge tyres?
Spoke keys?

There comes a time when you just have to recognise that these things are properly left to archaeologists - and that life will go on anyway.

Have you considered a Harris tweed jacked with leather elbow patches?

Unleaded fuel makes reading plugs a whole new game. It is nothing like your dad's era, it was simpler then.
But either way, to get an accurate reading you have to turn off the ignition at whatever load you want to read, shift to neutral and stop the vehicle. Simply pulling a plug and reading it will only tell you what the engine was doing when you shut it off, idling, in this case.

A good article here (http://www.angelfire.com/fl4/pontiacdude428/Readplugs.html).

I remembered that much.:d This plug came out of my chainsaw.

My dad mostly read plugs on alky racing motors. . .

There is not a lot of owner adjustability in modern vehicles, so plug reading for me these days is like I think yours is, for small engines. Chainsaw, lawnmower?
