Place a bleeder around the perimeter of the part. It looks like fiberfill insulation. This allows the vacuum to continue pulling resin and bubbles out of the part. Put a bunch of it around the vacuum inlet, too. the bleeder prevents the bag from sealing off on the mold backing plate.
Also, don't put too much resin in the part. Use a squeegee and put in just enough to completely wet the fibers. This will allow the layers of fiber to compress together, rather than squeezing excess resin. It also prevents filling your bleeder with resin.
