Hi everyone I am new to the forum and had a question about the fluidizer attachment for the dual voltage gun. I am getting ready to try it out on a 4.6 dohc timing cover. I have used the gun without it several times now and seems to work pretty good. My question is: I have a hole in the bottom of the fluidizer and there are several small holes drilled in the sides of it but they dont go all the way through. Is this how its supposed to be or should I drill the holes completely through.
