    my mom ordered a gokart for my brother for christmas it came in yesterday and I spent the whole day building it poured some gas in it then started and let it idle for about 20 min. after that I took it out for a spin and ran out of gas(figures) after running back getting gas bringing it back ect then having to push it back because it wouldn't start. again once I got it into the garage it started then shut it off for the night. now I come back this morning and it won't start and sometimes makes a rapid clicking noise. any ideas?
    oh yamaha 250cc water cooled engine

    you changed the intake?

    I don't know if it is the same on go-karts but on bikes theres like a little valve which lets more fuel in.

    I don't really know much about these things, just something I remember, I am sure a more able member will have some sound advice.

    I sometimes work as a side Mechanic for Ancaster Karting which might help :D

    I will assume you checked oil and you are using the right grade.
    Check the gaps on your spark plug, off the top of my head your are looking at a gap between 0.8-0.9mm.

    Check fuel lines for any blockages, can becaused by sediment in the tank going in to the pipes when it has been run dry.

    When it was first built did you rag the crap out of it from new or have you been gentle with it?

    I was gentel with it the motor came pre assmebled and I am going to check that stuff now

    nope none of those are the problems, it sounds like its stripping a gear after a few seconds trying to start it. I am assuming this is a bad sound

    A rapid clicking noise? only thing i can think of making that noise would be the starter or maybe clutch.

    Its a pull chord type starter? with auto clutch? 4 stroke?

    What kind of thing does it do when its not starting? does it just refuse to do anything? dose it almost go but not quite? are you chokeing it? if so what differance does it make? When it starts does it start easly?

    could be anything by your description im afrade, sounds like the starter isnt engaging properly tho

    I'm not entirely sure I can't really tell without hearing it.
    What model engine is it?
    I am more familiar with Honda GX270 engine.

    Mmm, erm I am running out of ideas, although the Buggy looks mental!
    I think you may have to try the manufactuer, I really can't think what the problem might be. Sorry dude. Hope you get it sorted for your brother.

    You need 3 things. Air/Fuel/Spark. Check the battery. It should have 12-14 volts. If less than 12, charge it. Try removing the spark plug and place it against the engine block. Try the starter and check to see any sparks. DO NOT TOUCH THE PLUG OR ENGINE. Put your hand over the spark plug hole and crank the starter. You should feel gas splashing on your hand. If no sparks make sure the kill switch is in the run position. If no fuel check the lines for blockage. You may need to bleed them. Check the fuel/air mixture. Put everything back together. Remove the airbox lid and check the filter. Try to start it without the lid and filter. If everything checks out and it starts replace the filter and lid. If it won't start spray a LITTLE ether (aka starting fluid) in the airbox. It should crank up and idle fast for a minute.

    Have you called the seller?
