Hi Max,
Yesterday afternoon I had a Maori bloke bring in a Stihl whipper snipper, he wanted me to tune it. I had a look at the fuel and it was completely clear. I started questioning him about who put the fuel in and he said he did, but he got the fuel from his brother. After that he just kept mumbling and telling me there was oil in it but maybe he didn't put enough in and being very evasive. I said I couldn't understand what he was saying and then he stormed off saying he was going to take it back to where he got it from
