Iv been looking about the internet for an answer to a few questions i have but havnt really came up with much. I also asked about some scooter forums but i got some pretty vague answers or just none at all
This is 2 stroke related and supose its a generic problem so thought i would ask on here and people are bound to have ran into the same problems.
I got a 100cc 2stroke scooter to run about in for the good summer weather, i got it really really cheap and fixed all the problems on it but its smoking really really bad, i know the bike sat for a number or years, some people say that some scooters just smoke bad but this is beyond a joke, im sure the police would pull me over for it, its not so bad on idle but once build the revs up its seriously bad.
Iv changed the 2 stroke oil for fresh stuff as the stuff in the oil tank could have went bad and put a new plug into it, it idles fine and revs fine, i took the plug out and checked, it was really really black and sooty so i thought that it could be running rich. So i cleaned the carb and checked for a air/fuel screw but found nothing, droped the needle 1 notch and its still smokey and ran worse then before, splutterd like crazy.
Took the head of and noticed that the piston has a small amount of play side to side (Is this normal) and noticed that the piston itself had what looked like black oil on it. im thinking that it needs a new piston and rings and fresh seals around the barrle and head, has anyone else ran into the same problems or can shed any light, its also a little difficult to start, have to give is some gas.
