thanks for the help, getting to the internet is difficult, i have to find a free computer at school. i bought an inline fuel filter and will install it later. the bike has about 550 miles on it, i don't know if this is very acurate though, it's almost thirty years old. and yes i did touch the air intake screw before i did my research, i think i reset it to the previous setting. the battery is fairly new, within a year. i use a generic two stroke brand from wal-mart. thanks for any input. i'm an amature at best and learning fast, but i still need plenty of guidance.
