  1. I needed new throttle grip and kill switch housing, installed it, the wires on my magneto and motor are blue and black, the new k.s. Was yellow with red stripe and green, connected green to black and so on,, adjusted my carb needle reassembled with the needle spring fully open due to it not being placed all the way in tried to run it and no good after messing with it for a while got that sorted and now it'll start but its very quiet and no pull/power. WTF is going on??? someone?? Please and thank you

    Check the exhaust cap to see if there is a lot of oil in it.... This can cause your issues

    if it smokes too much, your motor is full of fuel keep it running till it clears out

    if not smoking, check slide is moving properly and needle is still connected in slide
