Could having no air filter on my mini bike make it not start?

I have a 1985 suzuki jr50 mini dirt bike. Got it off a friend he said he didnt know if it ran. It has compression and spark, got a new spark plug too. I can spray starter fluid in the intake and it will fire and start for about 2-3 seconds then dies, cant figure out why. Only thing I can think of is because there is no actual air filter in it. It has the casing but no actual air filter. Could this be why it wont run or what?
