I brought a chinese saw off ebay which I have run 3 tanks of fuel through and it has surprised me, its still going!
I was giving it a service yesterday and found the air filter had not been doing its job, lots of saw dust getting into the intake! I think this saw is a Stihl copy? Does anyone reckon I might be able to buy a Stihl air filter that will fit? Or at least a foam filter to fit?
