In fact, you'd just pass the case over to Dept of Fair Trading here and the govt would persue it. It's illegal for both manf and resellers to promote a product to do something it is incapable of, snake oil.
Running a few tanks of juice through to mill is far from abuse.
Like I said, they rebuilt mine.
Stop comparing cars and cement mixers to chainsaws, they're not 2 strokes.
The question has been raised and asked before about 2 stroke performance, they're either flat out or at idle and not designed to perform at half throttle .... that's from the very saw guys themselves, do some searches.
I have noticed the same with 2 stroke brush cutters and lawnmowers, there's one speed, flat out. I had a Kawasaki straight shaft brush cutter, it had a half throttle lock which I used a lot for inverted edge trimming instead of holding the trigger. The engine carboned up and had to be de-coked, the dealer told me to run it flat out, that's what they're designed for.
This does not mean you dont warm up or cool down your saw either, that's common sense and there's some words about that in the manual.
If in fact at normal settings and r's the saw on a hot day siezed after repeated tanks of fuel then you wouldn't have to be Einstein to figure out that the piston/ring tolerances are too tight to the bore or the cooling system inadequate. Some-how I think companies like Stihl and Husky would have done those trials.
It's hot here often, on some land clear jobs I've had that 66 ripping for hours, never missed a beat. But like I said it's not lying on it's side .... if that does make a difference.
