Ok here is what happened. I notice a four wheeler at sitting in the weeds at my moms house.she said it had been there about a year and that she got tired of messing with it and told me to take it. i cleaned up the carb real good (it was pretty nasty) and put it back on, cleaned out the gas tank , put some gas in it. i was surprised but it started and ran fairly well. i rode it a few times, never for very long and then my little girl lost the key to it. since i couldn't find it i decided to just use a toggle switch and bypass ignition. when i got it hooked up for some reason i pushed the kill switch on the handlebar to off. when i did that i heard a pop which turned out to be the fuse. slid that switch back over, replaced the fuse, and tried to start it but no luck. It had been running good enough that it would start first pull with the rope. now it is not getting any fire to the plug. Does anybody know where i need to start troubleshooting the issue or why it blew the fuse. Any help will be appreciated.
