    Hi i have bought a blaster a couple weeks ago.
    And it runs fine.
    But now i start to notice it smokes a pretty hard.
    The 2stroke oil tank hat been removed by the guy i bought it from.
    It only smokes when it is on high rpm and hot.
    Does somebody know why it does that and how I could fix this.

    Unless you have a weedwhacker engine, STOP using the wrong oil !!
    Is the smoke whitish and stinky? Have you done a leak down test yet? Is trans oil full?

    Clean carb, set float , and adjust idle and air screw. Clean air filter.

    The smoke is white and stinky like you said.
    and it leaks a little from the output shaft when it is hot. but my trans oil is full.
    is there a big difference between 2stroke oils?

    Difference in oils ??:rolleyes:
    As much difference between a 2 stroke and a 4 poke

    Outboard : lower rpm, constant rpm, colder run temps
    Weed whacked/chainsaw: small displacement, throwaway tool

    Yamalube 2S will suit you fine, available for injection or premix

    Stinky smoke is an indication of burning trans oil.

    DO A LEAK DOWN TEST !!!
