I have a duratrax Torq .21 engine that was bought used. I set up the carb and pulled and the pullstarter broke. It seems that the knot came out of the hole. I fixed it and it kept slipping through. I drilled more holes in the disk and tried all different knots and the rope still either breaks the plastic or slips through the hole somehow (maybe because of the wax on it but I'm not sure) I got the engine running one time but the rope keeps breaking. I tried fish line instead of rope...it broke. It was only 20lb line anyway. I can't even turn the one way bearing by hand. Is this normal? I will probobly buy a new pullstarter but I don't want to if the pullstarter isn't the problem. If anyone has this sort of problem or can help me out it would be appreciated. Thanks
