about 50cc,s of petrol, and if it rev,s ok then its most likely a fuel supply problem (can you hear the pump running ?)weting the air filter with petrol just a bit ?
an what should happen if do so ..
i have the big cap off the top tank part i have pipes taken off but it only takes out just the top cover were the wires connect, it looks like the pump is mounted inside the tank am i rite ??
