Thread: Big voids in baits?

A new issue is popping up! When I inject my molds with chartreuse to cut body section out add primary color I'm getting huge voids in 1/2 of the 12 baits. Could I be sucking air past o rings? How often do you change? I'm going to take off end of injector and fill. ( I know) dangerous and try and see if it's a air issue? I think it is? Have ya'll had this happen to you? Lot of time put in then disaster! Here are some that came out ok?
