G'day Mitch,
I use mine alot, they do real work in goat conutry down the back.
I am interested in your findings. I havnt noticed this yet.

I have had all kinds of tensions on these belts in the past,.
I try to find the happy medium.
Too loose & the inertia isnt there for starting & rips the cord from your hands too tight could give engine wear.

I am still not sure about the suggested tightening procedure on the sticker.
Why are the washers there??
In my case if I hit something I like the blade to swing back & the belt to give, so I lean towards a looser belt tension.


Happy is he who penetrates the mystery of things.
