Hi I just bought a new revo 3.3 and let me tell you it is great. I would recomend one to anybody interested in rc cars. A few weeks after having my car I noteced that the part were the fuel and air meet ( excuse me for not knowing the name I am new to the sport) was leeking fuel, so I unscrewed the little nob that you use to adjust the fuel air mixture and I noticed that it was striped. So I purchushed a new carburatar assembly(was not cheap) and installed it. I noticed there soon after that there was a crack on the carburator body. I do not know what to do. Should I buy a new one for almost 50 bucks or coat the crack with some epoxy. please help.
