Looks like you got yourself in a jam jam princess, the oring goes on the same bit of pipe that your wavey washer is on,then push your carby over the pipe and slide it on over the oring this should give it a: tighter fit so first the wavey washer then your oring then you carby and it looks like you got the angle of the carby right. The white thing is a poppet valve . The poppet valve needs to
Have O on it and I think you need to turn it so the O faces in the direction of which the fuel goes in . Someone will probably be able to explain the poppet valve a bit clearer . Hope this helps you.oh and id say it's a 160.cheers,and there is a groove for the oring to sit in .
