Ok so I was modding my blaster by taking off the airbox lid and putting in a new airfilter. I asked around on here and people said that I should try anywhere from 240-260 jetting. I put in a 250 and I lost a lot of power. The top end and midrange were the same but there was no low end. It barely lifts up in first without the clutch. I tried messing around with the air mixture screw with no luck. I think it may be running too rich because it doesn't have the throttle response it used to and when I have the choke on, it bogs awful. What should I do? Should I try a 240 main? The only mods is no airbox lid and toomey silencer.
