"I'm not ready to take on a guy like that," =/= "I'm not ready for that yet!"
BlackBeard's plans and goals might have him going against Akainu or other Admirals later on down the road, so he could easily be implying that he's just not ready for that part of his plan to come into play yet..
Not once does he say he's "scared to fight Akainu" or that he's "not strong enough".. he's just saying he doesn't want to go for that at the moment..
BlackBeard had no problem fighting any Admiral (Akainu included) during Marineford.. it wasn't until Shanks showed up that Teach decided to leave..
