I know not many people have this gun, but I'm just praying someone can help me get it working again since I do lean heavily on it. Basically, the burst doesn't work anymore, and it's auto all the way. Semi still works perfectly, and I've no idea where the burst sear is or how to check if it's just out of alignment or if I need to replace it. Considering all the instructions are in Japanese I've no idea where to start. Thanks for any help.
