    Lazy Ingenuity, 29cc 2-stroke

    Ok, right.
    I know this doesn't go into Sports, but it IS a bike.
    Kinda.

    TL;DR, BOTTOM OF POST

    Anyhow, the predicament is as follows.
    I finally made my shit-scared-of-bikes friend go halves in a wee-thing.
    It's 29cc's of 2-stroke, centrifugal clutching goodness. The f***ing spark plug that had to be replaced, came from a hobby shop for big RC motors. I kid you not, Repco had to special order it in.
    After I refreshed the fuel mix, as it had gone stale, the beast fired into life with OVER 9000 PULLS.

    We decided, that at 9pm (Yes, we were determined goddamn kids) we should find somewhere else to ride the noisiest goddamn thing we had ever heard, like a car park. You see, it didn't really go anywhere, it just made a fuckload of noise.
    I told him we should wait till tomorrow *it was Friday back then*, but he wanted none of it. He was totally fucking stoked we got it going, and he couldn't get that grin off his face.

    Too scared of bikes my ass.

    Anyway, we got up to Verrans corner and tried to start it, hoping we'd get enough speed to make it past the speed camera and be able to carry on up the hill somewhat. Wrong.
    The pullstart mechanism, long story short, was totally rooted from so much pulling beforehand. We tried putting two Allen keys into a hand drill to start it, but there just wasn't enough turning going on.

    No, you can't get a replacement, it's impossible. Srsly. They stopped making those about 100 years ago.
    Not unless you upgrade the engine. (Which it seriously needs)


    Anyhow, 5 weeks later, I went to the wreckers today for a starter motor and they wanted t sting me about 60-120$, about half the cost of our beloved beast.
    With that, I went to my mate who's pretty mechanically minded, being an engine re conditioner, fellow biker and all, asked would a starter motor give the engine enough RPM to run under its own. Gonna take a picture for him when my mate comes home, so he can help out some more.

    I'll post up the detailed'er pictures later, so I could get some ideas from you guys/girls.

    What the hell was my question... Uhm.
    Very important, as a ballpark figure, does anyone know what kind of RPM i'll be needing to start the average weedeater motor?
    I know it's more than a hand drill.

    Where the hell would I go for a cheaper starter motor?
    Would a bike starter work?
    Should I even bother?
    How much of a ball-tie-er would putting a new engine onto it be?

    20 Questions is over.

    Pics related.

    I'll actually take a video of its blistering acceleration if it gets running.
    There is no way it'll start on a flat, without man power.
