Hello I just bought a 1990 Blaster and it wasn't running when we bought it. It has been sitting in a garage for a couple years. Dumped old gas out put new in. Added new 2 cycle oil. Spark plug hasn't been replaced. Seems to give off a little spark when we tested it. Would not start off kick-start. We push started it down a hill and it started and it was revving really high without even giving it gas. This was while in 1st gear. Tried using kill switch and it wouldn't turn off then turned key off. After that we tried a few more push starts and it would start for a second and then die. Don't know much about these since its our first one. Any help and direction would be great! Thanks!!!
