My CR150 started leaking gas out of the overflow tube. I had an old carb and changed the float and needle and it has made it alot better, but it still leaks a little. A little help please.
Did you check the fuel and float level? Also install the carb into position without the float bowl on it, put enough upward pressure on on the float assembly to close the needle valve, then turn the gas on and check operation and for any leaks. Your bike isn't old, so I would have to guess that you bought some other carburetor off of an older motorcycle for it.
