I know it might not be what you want to hear but when rigs come into the shop after being "repaired" and they have a problem now you ALWAYS look at the last thing that was messed with. You need to look at everything you had to remove to do the job but if it is turning over faster than you remember that is because you have less compression now. Start over act like you have done nothing and do everything by the book and fix whatever it was you accidently messed up.
