ok so i was driving it around the yard letting my siblings drive, the youngest is 4. everything was going good, so i decided to take it out on the road to open her up and let her cool down. i get up to 30 turn around and start coming back. about half way back i get thumped in the back by something (figured it might be the fly) nope, it was the driver. i found 1 of the fly weights, no garters; and the movable sheave. i know where i can get some used parts for cheap, but i'm wondering why it decided to, for lack of a better term, 'detonate'? when i first got thumped, i turned to see what had broke, i thought i saw a shredded belt getting ejected, nope, still good. the system of mounting i had been using is the same since first installing the TC system. i tighten with a wrench, then with the wrench on the bolt, i pull the rope (it acts as a wrench). that might be why the rope has broken twice.
