You would hate my old 1989 Ryobi lawn Hornet with lawn sweeper attachment. It sounds like a WW2 air raid siren. Just be grateful I use it once a month if that and only for about 10 minutes max. You would prefer my friend's Weed Eater blower (aslo an Electrolux company) which is incredibly loud but at least has fixed throttle settings.

Not sure if i got that quote bit working right Mowerfreak.
That's the same leaf blower i normally use - except mines yellow since its a McCulloch - bought from the tip with the common loose cylinder head - bore wasnt too scored though. I saw the data sticker on it when I tore it down to fix - it said (effectively) 'Designed in italy, made in China and assembled in America'. i said straight out that it would probably try and kill me somehow. It did.
Turns out McCulloch cheaped out and put a thread on the crank shaft that will undo its self if not torqued to the point of shearing.
Tuning carby, I hear this metallic pinking noise (the little end bolt) so i let off the throttle - the spinning was the only thing holding the blower impeller, and metal mulching blade plate (its supposedly a vac as well) on to the crankshaft.
As soon as the momentum went, the impeller dropped off and the mulching blades went flying out the side (away from me luckily).
Now the nut is thoroughly loctite'd on

Those old Ryobis were good - I've grabbed 2 from the tip, the bores still had factory honing marks on both. I quite like those Ryan USA engines.
On a side note, I walked past a guy using an Oleo Mac Leaf blower today - sounded great and was amazingly smooth and quiet compared to the domestic use half cranks.
