I bought my youngest a new mini Raptor 80 about 3 months ago. Now, after cleaning the carb, air cleaner and making sure it has spark it still does not want to start. What should I be looking for?! This is EXACTLY why I bought him a NEW freaking quad, we have two older YFM 80's, an 86 and 87 and they did the same freaking thing!!! Any help would be appreciated!
