The one that went on my 066 came from Garden Hire Spares and has been fine so far. Hasn't worked as hard as it used to when it was my primary milling saw, but has done a bit and seems happy enough. Not entirely sure what brand it ended up being. Golf and Meteor seem to be recommended if you can find them. Episan may be OK too, which I think come from Greece (Spud is your man for this question really).

 

Which side is scored - inlet or outlet? Do you know why it failed? The former can be diagnostic of the latter if you don't actually know. It's significant, as using new pot and piston kits as a diagnostic tool gets very expensive. This is why not pressure and vacuum testing (or having it done) is a false economy in my opinion.

 

54mm is standard, so personally I'd stick with that. There was an 066 Magnum, the early ones of which had a dual port muffler and a heavy duty crankshaft. Even that didn't have the 56mm bore, so I'd leave it alone myself.

There is scored and scored, look at the whats on my bench thread and see what I have done in the past! I would always take the OEM cylinder in front of a Chinese aftermarket one and once cleaned, use a Meteor piston.

 

Here is a real bad one that had a great slab of aluminium ripped off the piston, it cleaned off and left very little damage - as long as the surface is smooth and the plating is good, it will work well.
