    Replacing needle and seat in yamaha yz80
    Hey guys,
    I had fuel leaking out of one of the outlet pipes on the carbi on my 1998 yamaha yz80, I was told by the guys at the store that I needed to replace the needle and seat to fix the problem, I have ordered in the replacement part from yamaha and am waiting for it to come in but I would like to do the job myself, but being not very experienced in this area I am seeking help as to how to do it (has anyone here done it before/is it a relitively easy job to do etc etc), also I do not have a workshop manual for the bike.

    Any help would be greatly appreicated,

    Cheers,
    Ben

    Could you please elaberate on that and if possible some pictures, I took the top off and there's the spring attached to the throttle assembly, I'm assuming that the part at the very top of the carb is the needle/seat but how do I get that out? I put the carbi back in the bike but now the screw has come right up and there is no throttle response.

    Any ideas?

    Any help would be extremely appreciated
