well, as of now, my infamous 1978 Puch Kromag is in critical condition! I was riding it around when the engine started making a high pitched whistle. I knew that from past experience that meant only one thing: the long bolts that held the cylinder together got loose, therefor making the whistling sound from the ever-so-small crack! Solution: Simple! Tighten the bolts! So I drove into my ped repair shop (AKA my back yard) to tighten them. I started tightening the bolts when I realized that they weren't tightening but just spinning in place! Obviously, they were stripped. Solution: Go out and buy some more. So that's what I did. I came home with the bran new bolts, and started to screw them in. Again-g, they wouldn't tighten! HOW COULD THAT BE?!? Those are bran new!! Then it hit me like a cement truck! unlike the outside (bolts) being stripped, which i could easily replace, i stripped the inside! (engine) which would be a little more costly to replace! I don't know what to do!! I'M PANICING!! SOMEONE PLEASE HELP!!!!!! I can feel the ped getting sad when I turn on the lawn mower. He misses his ability to run. I need some advice (or a new engine, but that ain't gonna happen) so please offer it if you can. <sniff-sniff> I think I'm gonna cry!! Thanx, Rimas!
