Was riding in yard w my son on his quad. One lap around house and it just puttered out and died on me.

Always starts on first pull. Never had this happen before.
Now I try to start it and it's got nothing.
Took the plug out and cleaned it. Looks good. Also had gas smell so I don't think it's a carb issue. Which has recently been cleaned anyways.

Bike has an electric start but when I hook up a battery it still doesn't work so I obviously have an electrical problem somewhere but haven't gotten to thst yet.

Just got this three wheeler about a month ago.

Please help!!!
