Hey guys i have 2 sh.18 one is brand new in the box the other one about month old with a week old carb, both of the carbs are locking up this is my 3rd carb that has locked up! the sh.18 brand new haven't takin it out of the box the carb was nice and loose just like the one i order from yall about 2 weeks ago, with end 5 tanks more or less i have had 2 carb lock up they still move but there not loose enough for the servo to move them? i dunno what else to do!! i have adjusted the servo i have replaced the carb once all ready and they still just keep locking up, thats 24.99 a carb this is my 3rd one!! i also talked to mike about my lightning about the idle screw not working!! the lightning was brand new not even 2 tanks of gas threw it, i worked with it for about 30 mins and got it working but now its doing the same as the sh.18 carbs its not as tight as the sh.18, all in a summary so when i adjust the servo and i adjust the carb the thottle still sticks and runs high rpm intill i press my brake on all 3 of my redcats the lightning and my 2 volcanos
