Hello again AVB, and Hearty Thanks for the words of encouragement!
Yes, I have to say - I was feeling a bit like a little doggy there for a while, who wasn�t quite sure whether he was being lightly smacked, or just vigorously patted� Ha ha ha! Anyway, he might be a disciple of shock tactics. If I was a bit younger, they might have done me some good!
For what it�s worth, I can sympathise with the �maximum throttle� train of thought to a certain degree, but only so far. For example, mower engines with alloy blocks, but without cast-iron liners, might theoretically suffer slightly extra wear when loaded up at any speed other than full throttle (which is still only 3000rpm or so) due to the vibration caused by their relatively longer strokes. But as for grass-trimmers, with their relatively shorter strokes, a constant 10,000 rpm seems like complete overkill in light of the load in question, as well as a waste of fuel. It�s also virtually impossible to neatly bevel your edges at that speed, so I�d have to start �trenching� them all (which certainly isn�t as pretty). But anyway, I digress�
I didn�t end up giving the Inlet Needle Lever a tweak yesterday after all, but I�ve dialled in another 1/8th turn or so of richness to both mix-screws as a first step, and she�s now burbling more at both idle and full throttle. I wont really know the full outcome until I have to do all of the lawns all again. But if she still wants to play hard-to-get when that happens, well - it will definitely be a case of carby out, lever adjusted, and muffler de-coked. If that doesn�t work, it could well be time for a new FS38 (because the "36" also needs a new Rope Rotor...)
Very Best Wishes across the Moat to you AVB!
Moby Mick.
