I have recently just started my Nitro 4-Tec with the Trx 2.5 engine. When I started it up, gas just started to spew out of the exhaust pipe. It was the first time I had started it up in over 3 months. Also, the gas that was coming out reached out at least 3 to 4 feet. And after only a few startups, there was only half a tank of gas left from it only running for about 5-8 minutes. The worst part was I didn't even get a chance to get it on the road! Any suggestions?
