Series II Jota timing marks

[RCGBOB44]

Brain picking time chaps.

I suspect I might have an ignition fault on the jota so forked out for a timing strobe to check the advance.
With the pick up is connected to the left hand plug lead the strobe shows the rotor advance as the revs rise and the timing marks seem to line up.

When the pick up is connected to the centre pot the strove shows the rotor advance but its lining up on the rear pick up coil, if that makes sense, and not the same timing marks as the two outer pots.

Now before anyone goes loopy at me for being stupid, which I already know, I am fully aware that the bike has a 180 crank but should the timing marks line up for the centre pot  the same as for the outers?

The timing marks for the centre cylinder would be 180? opposite to those for the outer cylinders... sounds sort of logical for a 180? triple, dunnit?

Please do not rely on the marks embossed on the stock ignition base plate, these rotate with the plate, so, in reality, you can't really know what's happening, the marks always line up.  You need to make new marks on the rim of the timing cover where the base plate is centred and go from there.

No real need to determine the exact ignition timing for the centre pot if all is well, the base plate is quite precise and the pick-ups are usually actually 180? apart.  What does need checking is if the advance is working correctly.

Thanks Piet you've confirmed exactly my own thoughts.
New ignition time methinks.
