Do you mean that the bolt were tightened down to 1/16 from the base? Or that the U-shaped base of the limbs do not slide in all the way to the bolt?
The first situation would be over-tightening the limbs - there should be some play and the limb will be secure when it is strung. The instructions should tell you not to tighten beyond 1/2 turn from the bottom and 1/2 turn from the extreme "out" position, or something like that.
(My Hoyt manual says not to loosen beyond the point where the head of the bolt is beyond flush with the riser and there should be at least 6 threads engaged.) On the other extreme, if you cinch it tight, you may not be able to remove the limbs.
The ILF system is not like bolting a Black Widow or other TD where you tighten bolts all the way to hold the bow together.
Regarding the second situation, I've seen some limbs that will not go far enough in to let the "U" come in to the limb bolt or get a "click". This is often a simple problem with excessive lacquer on the base or different tolerances between manufacturers. We recently had a new limb that only needed to rub some string wax in the "U" to slide in far enough. Other have suggested white automotive grease (lithium grease?) Some have gently filed or sanded so it goes in.
