Fitting the wrong index spark plugs

[eq1]

That's probably the clearest graphic yet (1st pict post #29) showing the correct clocking of our indexed plugs. Looks like you got it right. Bugone, though, last picture in post #20, seems to have it 180 degrees off...

I guess it all comes down to whether the position of the electrode in the 2nd picture in post #29 is accurate. Would be funny if we were all working along the guidance of a photo that wasn't correctly indexed.

I think you're right though. I've mentally rotated the wrong way. Looks like ill be doing a bit of tightening of those plugs. Thanks.

It's right. There was another long thread a while back where a bunch of us worked through this, more or less.
New Spark Plug Indexing

I've re fitted the plugs now so that the mark on my spanner is 'west'.

The torque felt just about right, I could feel the washers crushing. Id be worried turning them another 90 degrees.
