Honestly not trying to be funny but get rid of the bad gas and flush it out. use nothing less than 90 octang gas mixed with 3 1/2 ounces to 4 onces of a premix oil and it will make your motor last for a good long time. I prefer Amsoil dominator race oil it's like 10 bucks a quart which is pretty cheap for the most part. You mix the gas and oil together and pour it in the gas tank via seperate jug to be exact because it matters. If you have a square ish looking box/tank opposite of the pipe your premix oil will more than likely have to poured in there but check if it is still connected by hoses to the side of the carb. Most people get what is called a oil/premix block off kit for like 20 tops cause their faulty in most cases and arent good if you want to keep your new blaster running healthy for a while. Post more questions or pictures if you can. Me and everyone else will gladly help. PM me if ya need help with things.
