Default Yamaha YFM 350 Raptor wont start

Hi I have a YFM 350 Raptor and I'm new to quads.
I've ownd this quad for two weeks after buying it from someone who hasnt used it much. (In a year they from 2011 MOt to now they only had an extra 20miles to the clock).
The old petrol was in there before they topped it up (full tank)
I've used it since then and now it wont Idle/start.

Can anyone out there give me advice, Once started it sounds like a bag of s***! then reved its even worse, then put into gear it then stalls.
Wont start again.

Could this be a carb issue as it has not been used often and sitting there with the old petrol in the tank with new as a top up?

Please help, im new and need the advice?

This was the exact scenario I was in when I bought my Raptor about a month ago. The old fuel probably has the jets clogged up. This was the case with my Raptor. My friends and I took the carb apart and cleaned it out real good and sprayed each piece off with brake cleaner to blast out any little dirt particles or deposits. When we put it back together it started right up and idled great. I added a little "Start your engine" fuel additive to the first tank I ran through it to help clean anything else out and after a couple tanks and a new spark plug it is running like a champ! But you should disconnect the fuel line into the carb and drain all of that old gas out of there first thing. Then maybe pull the carb apart and give it a thorough cleaning. I'll bet that she starts right up after that!

Will remove old fuel and clean out carb.
