I can tell it's faster and it's getting a lot more air now. when I took the stock one off it was all black and oozy. there is one problem I have is when I start is and pull the throttle it doesn't go anywhere and it just makes a loud dead sound but then it will kick on after a minute. Also, the guy I bought it from took off the oil thing so I mix the gas myself with the oil.
I might have something lose and that's why I'm having this problem. Maybe its getting too much air
