get comfortable on the jump youre going to throw it on, its always good to throw a regular 7 before so you know how hard to throw the corked 7. pop with your weight centered, throw a 7 while dropping your shoulder(tucking during the spin helps a lot), start spotting the landing around 540ish and land. you shouldnt have any problems with uncorking it, or else youre just throwing it wrong. i think if you watch john kutcher's POV video it would help you with awareness in the air during cork 7's
