hiya people new on here. well i have a smartech commando nitro car and yesterday i were playing with it, it had 1 tank and then filled it up the second time and thats when it went wrong. my pullstart will pull out but it does not spring back, just moves bit by bit as the flywheel turns. rather confused as ive taken off the pullstart, rebuilt that and it moves smoothly and springs back, taken back plate off, the one way bearing seems a bit touch and go, it were rubbing but i turnt that and the nut on the other side a few times and it moved smooth but if i take it out the engine again it rubs abit. when the engines all together i took the glowplug out and pulled the pullstart and it will spring back as there is no compression
