Hello,
I hope you will help me! My et2 sometimes starts to coughing (I don't know the exact word, but it lost the power and khrkkk-krhkk-krhkkk, like drinking straws, when the bottle is empty.) It happened randomly, but more and more often. Today I've changed the spark plug (it was only 3 months old) and the problem disappeared. What can I do? Is the mixture wrong? And how could I repair it?
Sorry about my English! I wrestle with it, and always lost...
