its not the losi that is making the carb stick obviously if your linkage is not correct it will bind and stick but people need to get it correct that its not the losi causing the issue its happaning on all cars and fuel causes carbs to stick as well...open your carb up and buff (polish) not grind.. the needle and the slide where the needle sits, clean it and you should be fine..if you guys have questions about the carb call Chad at Trinity and he will explain whats going on....

so what kind of run times are you guys getting with those pipes your talking about ?????
