Is there a good website or even a book that gives you a step by step on the ins and outs of this. I am 100% new and getting 100% frustrated with this. I have broken it in, now when I start it the wheels spin, I don't know how to adjust this, I know nothing about the carb (which screw is which) and I have also smoked a spur gear and slipper pad. This is getting to be a great start.
