Hey, new here but I can tell that I'll be visiting often. Long story short, I bought a Blaster with a bad motor and them purchased a motor with a new top end. I put it in with all the parts from origanal setup. So I have a Factory seven pipe v-force reeds and a uni filter. The carb has a 300 main jet and about 1.5 turns on the air screw. She fires up and runs a few then it bogs out and stalls. When it does run long enough it will not idel. Any feed back would be great. :-/
