    I would try a new spark plug first, If that does'nt cure it then its time to look elsewhere, Even though you have a spark, It may be breaking down under compression

    Cheers

    waterlogged killswitch shorting out? if no spark from a bad plug you may of flooded it unknowingly, then after swapping to a new plug, it wouldnt fire becuz it loaded with fuel maybe.

    no if the switch was shorted it shouldnt spark at all.

    the only things you can do are

    1. pull the spark plug out, turn it all on, wot it and pull your ass off. if its really flooded, you can turn it upside down like you would with a nitro and give it a few pulls. keep the exhuast of the buggy downward and you can get some of the excess gas to dump out the exhaust. but basically its keep it wotted and pull your ass off.

    if you don't keep it wotted when you pull it over, you ll suck more fuel in and it will continue to flood a bit. eat your wheeties, if its flooded bad. you ll be pulling for a while.

    If it was me dude i would be putting a new ring in straight away whilst the head is off checking head/piston ! drain any excess fuel out if any? make sure carb and filter is clean and dry! And you will have to take the fan cover off so you can check the kill switch clean/dry/lubed! All back together!
