    Thumbs up Ok...

    First thing just get a pullstarter, there are 2 models for that engine.
    The cheaper plastic units approx $25-$35, or the aluminium heavy duty ones with the aluminium pullstart claw approx $45-$55 (yes there are cheaper quality ones, but gereraly speaking...cheap = crap.

    Once you got pullstart bolted on its time to check for spark.. DO NOT TRY ANYTHING ELSE BEFORE YOU DO THIS !!!!

    Remove sparkplug lead, unscrew sparkplug from engine... put sparkplug back into lead and rest the sparkplug up against the engine so that you can see the electrode tip (end of sparkplug that goes ...bzzzzzzzz.. with a spark)

    Next crank over the pullstarter while watching the sparkplug...if you see a spark, then your Coil and electric system is fine.... if no spark then you need new coil approx $28
    Make sure you clean the sparkplug with some fine wet/dry sand paper or use a new one before replacing back into engine

    Next, put a 25:1 mix (25 part of fuel to 1 part of 2 stroke oil) into your fuel tank, check there are no leaks from your fuel hose, filter or carburetor tap... if carb leaks... just buy a new OEM one $38

    Check that your throttle cable returns easy, if not, take apart the throttle controller and squirt some CRC onto cable.

    Now your ready to party.... put choke on, apply little bit of juice and pull away...

    If the bike wont start after about 10 pulls, then remove sparkplug, clean it and pullstart with the plug out once or twice...this will flush any fuel out of the sparkplug hole..

    Biggest mistake most do is keep pulling... it fills the engine up with fuel, increasing the compression ratio and then....snap...oh dear my pullstart broke... must be that cheap chinese quality...wrong.. its just you dont know nothin bout enginz drongo !!!!!!

    All the best... gota start somewhere.
