First, sorry for my english... At the end of last year, my motor suddenly stop. It ran only if i pump the fuel bulb. SOmeone told me that it was the fuel pump. I bought a kit to rebuild it. Now, it going well but it start after 10-15 hits... The idle is not going well too. It turn off alone and after i have to make big arm muscle! I know that is good for my health but not for my mental health... Can someone help me please?
