I’ve got a 2011 Beta Evo 200 that won’t start. The bike has got fuel, air and a spark. Carb has just been taken off and cleaned, jets are good. 
Any suggestions? 
Cheers!

Have you checked the compression?

Are you sure the engine has fuel?

Trouble-shooting section of the service manual will give you all the same questions we could possibly ask.

Haven’t done, but will get one done asap 👍🏻

Get compression test done? 🤔 It's a 2-stroke, pull the spark plug, remove the kill switch magnet so you don't get a shock, plug the spark plug hole with your finger or thumb and turn the engine over slowly. 

Spark is useless if it happens at the wrong time, once you know it has compression check your ignition timing or you can't rule out ignition as being the issue.

What is the recent history of the bike, is it fresh out of storage or was it running and then failed?

Bike is fresh out of storage, just been out and it did actually start.
Started with the choke but was absolutely screaming. Tried to adjust the idle whilst pulling the kill switch off and quickly putting it back on, so the bike wasn’t left screaming. Bike then died without the choke and wouldn’t start again. Something to have a play with again… run out of time tonight. 

Absolutely time to revisit the carburetor and if this is a carburetor where you can put the slide in rotated 180 degrees from where it should be, that is very likely the problem.  Should take all of 5 minutes to check that.
