I just purchased an Eclipse BS model from Iwata, bout 2-3days ago. I just went to use it for the first time, and already having an issue. I was doing a zenithal Highlight, which I used a different airbrush to run primer thru, but once I got to the part where you apply your white layer. I wanted to use my new Airbrush. For my white I use Tamiya XF-2 Flat White, along with their thinner (I only use their brand of thinner when using XF-2, since its alcohol based, nad my other thinners are designed for Water based acrylics). Anyways, the issue I'm having is. As soon and I push the trigger down for air, it starts spraying Paint before I had even pulled the trigger back. I am new to airbrushing. This is my first nice, somewhat expensive Airbrush. So I admittedly am still learning how to troubleshoot these kind of issues. I'm hoping one of you can help me solve this issue.
