I just purchased an adly 90 cc 2 stroke quad, needs a little bit of work. When i purchased the quad i noticed it wouldnt stay on unless you revved it up. I figured id work on it and try to get it running right. i let it sit for 2 weeks now it wont start. Itll crank over, throws spark, im sure its getting gas. Just need a little direction in the right way. Thanks ahead of time.

 

I'd try cleaning the carb.
