First of all like usual I'm really sorry for my poor English skills.
Mi piston broke, so I bought a new one. I mount it, but my cars doesn't start. In fact when I see closer the fuel doesn't flow inside the carb, even when i blow up the line. So I have huge doubt that I mount the piston in the right way. I read and watched several videos and the most clear was this: http://www.youtube.com/watch?v=Gk7vvPoXCTk (minute 8:32). He said The oil hole and the cut off of the piston goes to the front of the car or in direction of the carb.
I unmount the starter and the back plate so i can check if the piston is in that position. Here a pictures:
If I understand correctly the instructions my piston is in the correct way. But why the engine doesn't start?
I found another instruction on the web: (removed) the picture post it in there show the piston in the other direction and supossed the oil hole is looking backwards too.
I'm so confused , thank you guys in advance.
