    Hello Hpacordeon welcome to the forum.

    We are going to need a little more info? What type of motor are you speaking of? Is this a motorized bicycle or a moped/scooter?

    None of the kit motors have a starter and I have not meet anyone as of yet with a 4-stroke that's electric start.

    Leaking spark plug is easy fix. Maybe when you removed the plug you lost the crushable washer. Or possibly you over tightened the plug and the washer is leaking. If you have the stock spark plug then this is a good time to get an NGK or other proper plug and torque it down to specified number. Sorry, I don't know exactly what that is but it's easy to look up.

    You are correct, have not purchased a kit in almost a decade and I admit I may be a little behind but I'll catch up. Thanks for the link and correction.


    Hpacordeon sometimes the machining is not correct on the mating surface for the spark plug. I've had a few I had to go in with a dremel to get a nice seal with the spark plug.

    How tight are you tightening the plug? It is possible the spark plug washer has been crushed and needs to be replaced as Chaz has already suggested.

    I would try a new plug or replace the washer and see if that does not take care of the problem.

    Replace the Chinesey plug with an NGK B7HS which will have a better crush gasket to seal.
    Tightening instructions are on the box.
