i did everything the dvd said i used Traxxas 20% top fuel, and the ez start didnt work, so i got a pull start, i have had my carb at every possible freaking setting and the best ive gotten is it works ok but wont go past 3/4 throttle it stalls at full throttle, my local lhs is runned by a really nice patient guy who is great but i can never get the carb right and it bothers me and now my high speed needle came of and wont go back on...
