    You have to have a pull start to start it. That is what is keeping my away from them. Those things stink on mower, on bike motors they are worse from what I here.

    It's on the Grubee engine it will be called something and GGG-2 which is pull start and pedal start. I don't know what parts you would need to retro fit it onto an engine.

    I saw the one at Grubee a couple months ago myself. As I'm researching this stuff
    constantly I wondered how they got the centrifugal to dual start. I figure in time
    it will be quite popular as it would make it more user friendly for women.

    Yeah those brakes have been fitted on bikes with fenders for years now. It's not a
    problem.

    my 48cc dualstart starfire gt-2 grubee from gasbike.net
    has manual and centrifugal clutch,can be peddal or pullstarted

    Dual GGG model; Allows pedal starting as well as rope pull engine start. Uses a friction clutch as well as a special centrifugal clutch with over running clutch lock up to pedal start; Handle Bar Clutch lever must be in the engaged position to operate in centrifugal clutch drive mode. In disengaged lever position the engine is in free wheel mode separated from drive line. Note: A standard friction clutch engine can not be converted to GGG dual mode due to different crankshaft

    I had a centrifugal clutch on a Rupp mini bike when I was a kid about 40 years ago- it worked well, and I still used it when I took off the Briggs and put on a Mac 50 cart motor.

    I'd like to get one now, especially if it could still pedal start

    BECAUSE-

    I looked at the ad for one advertised on ebay with a pull start, and the assembly then sticks out the side of the motor an inch or more, and obviously would not then fit between standard bicycle cranks.

    Wider ones are available, if you want the expense and the more drastic deviation- search under "bicycle cranks" on ebay

    Back then you could get the Cent clutch in different size and teeth number for the minis.

    its alot harder to mount a pull start and cent engine than a standard one and its not worth the trouble.the engine is alot wider. i have one.
