Also make sure your latch rod hasn't burred up around the edge that latches, this will bind, I have heard the one you have sourced can have this problem.

Thanks Nick, I'll probably go the Mk2 spring route and replace the metal spring guide with a delryn and delryn washers if needed. Again thanks guys for your interest and inputs.
