Go to your local auto parts store and get some high temp rtv sealant. Also, check your fuel lines for any pin holes or tears in it. Hope this helps you out. Theres nothing worse than having a new RC that gives you those kinds of problems. Unfortunately, it can happen to any brand of RC so, don't give up. If all else fails, call CEN and talk to Notch. Hes a stand up guy and has helped me in the past with some issues I was having with my Matrix.
