I have always read the plugs from both type of engines in the same way Hooli. Dark to Light Tan as always, however that plug looks well black. On a 2-smoke this might be due to
1. Very very very rich mixture
2. Too much oil in the mix#
3. Plug too cold and not burning away deposits
4. Not being thrashed hard enough :D

Cheers Geoff

Cheers all, I wasn't sure if two smokes plugs tended to run blacker due to the oil burning.

My thoughts were to stick a new plug in, so I'll do so & see how it goes.
