Trophy 3, do I have a problem?

This is what I got for measurments.
I also measures HT wires. Number 2 cyl wire came up a bit short on Ohms.

Why primary is 1 Ohm not stated .6 Ohm?

All coils are PVL. Wires made in Germany. seems like PVL as well.

Spark plugs look OK, no fouling or other nonsense.

Looks pretty close to me, especialy when +10% is figured in. By the way I have two multi meters and one always reads voltage and ohms higher than the other.

You're fine. Unless you're using a precision setup (with 'kelvin' connections to eliminate the contact resistance) to measure 0.6 ohms, you cannot make that measurement accurately. In fact, that variation you see (1.0 to 1.1 ohms) is entirely due to the difference in resistance of the actual contact between your meter lead(s) and the coil terminal(s).

No worries lad.
