Assorted Gentleman - thank-you for your various replies, and my apologies for my own tardiness in getting back to you.
Mower freak - By all means I will try the 95 and the 50:1 mix, but don�t hold your breath, because it will be a good couple of weeks before I need any more petrol, and then need to actually use it.
Aussietrev & Gadge - Yes, in addition to inspecting the muffler, and trying to avoid being stung in the eye by a Mud Wasp when doing so, I�ll also attempt to rate the motor�s smokiness at both cold and warm temperatures when variously idling, accelerating, running at WOT without load, and also at WOT under load, when I wheel it out for some cyclone-aftermath-grade lawnmowing this week.
Best Wishes,
Mick.
