colej if I influenced anyone to buying the same heads, that they check them. That’s all
Ummm,
Actually that is "not all" since we all can read back in this thread.
You may BELIEVE that your intention was altruistic but you quickly posted that you agreed with Darpar that 'someone might have found a cheap foundry in China" and that you then fleshed out Par4Qc's post "I would think your idea of too much foam or the wrong kind of foam might be the issue? (that doesn't exist) Where did you get THAT from?.
A short time later you are bringing in your opinion on the screw... "My thinking was why would you need a plug if you don’t fill them?"
All of these posts are off what you are now saying was your original intent to help your fellow purchasers. So, which is it again?
