Considering your tools situation, I would also recommend shelling out the $120 for a cheap 80cc 2-stroke kit.
Or even a 49CC kit, About the same price, But It'll keep yer speed down just a little and help keep the law happy. AND everyone says thay last better because its less power than the 66/80CC and wont tear itself apart as fast. I highly recommend a 49CC china girl.
