so my unit (12.5 kawa) was seized up the other day....gas in the cylinder fromsitting...assuming a bad needle or float. found a bad float,replaced it (i am NOT a carb guy,just wingin' it). I changed oil, and started it up... SMOKE! i mean LOTS of smoke from the muffle. then when i cut the power, a gassy/oily mixture LEAKS from the muffler. I was a bit unsure how that needle attaches to the float...seems kinda cheap...but im not sure what i did wrong ideas?
