    just dont put the coolant pipes on it.
    step by step:
    1. take you old carb off
    2. put you new one on

    enjoy. lol

    take a good look at the old one before you put the new one on, always a good idea.
    The only pipes on a carb on these bikes are

    -petrol
    -2-stroke oil inlet from the pump.

    There may be a vaccum pipe if you have a vaccum tap. There could also be coolant pipes, depending on what bike you have. I'd get rid of them.
    The top 2 nipples coming off the carb are overflow pipes. Leave them alone.


    As said, each pipe is a different diameter and the nipples on the carb match those diameters.

    No offence or anything mate but if you're asking stuff like that i think you better let a garage fit it.

    You have got some jets, right?

    it will still work, these carbs dont have water cooling
    on your engine you will have two coolant nipples so just put the pipe from one to the other, they are next to each other.

    this is such a good carb mate, im running it. as i said to some other guy, the fule intake has been increased how ever the oil pump is still dictating the right amount of oil for the stock carb. as this is a bitch to ajust i recomend adding a small amount of 2stroke oil into your tank when its full of fuel an shaking it about as much as you can.

    i dont know which model he is running sorry if thats mis-leading, i was just saying on the old-uns its quite easy as there is a cable attachted to the oil pump and you just screw it in or out cant remember which and you see it adjusting the pump arm.

    mines piece of piss to adjust. Like you said steve. There's a threaded part on the cable
    just screw that in and out leans/richens the mixture.
