Re: where can I find the answer on here
If it is a Chinese in frame 2-stroke, the engine will not run perfectly until after the break in period. That takes about 2 to 3 gallons of fuel and 500 to 700 miles.
What oil ratio are you mixing your fuel at? 16:1 to 20:1 is the general accepted ratio for break in. I prefer 25:1 myself.
What color is the spark plug at the electrodes, the part inside the engine?
It should be a flaky looking brown to black, but not wet looking, when a heavy break in fuel to oil ratio is used and you have a good air to fuel ratio. If it is black and wet looking then you are running a bit rich on the air to fuel ratio, which I suspect you are. Check it and get back with us. Armed with more info we can help you out better.
