DS 50 problems

[BlasterRacer26]

Hey my nephew has a DS 50 that he hasnt riden in about a year and he finally wants to go riding and it wont start. We changed the spark plug,charged the battery and its turning over but not starting. I know before this thing has always been a pain to start. Usually we would clean the spark plug it would start. Anyone have any ideas on how to get it started?

I'd say the carb is all gummed up. Is it geting spark? I'd try cleaning out the carb.
