when i bought it it started after about 10 kicks and it died after about 2 minutes. i stripped the bike and rebuilt it, havent touched the engine except from cleaning the carb, new gearbox oil and 2 stroke oil. ive got a spark and petrol is going through but it just doesnt want to start.
also when i push the flywheel it moves slightly and makes a knocking sound then when i pull it back it does the same, im thinking its a bottom end problem and the top end looks like its recently been rebuilt, i can still see the gasket sealant theyve used.
Could be a leaking crank seal, take off the flywheel cover, and try spraying wd40 near the flywheel towards the crank, the revs should race higher, thats if you get it started mind, mine was a pig to start couple of weeks ago and needed choke to stay running, and that turned out to be the flywheel crank seal. As it was drawing air in, and making it run lean.

Aye, that was the problem I had, it wouldn't idle below 1800, without the choke being on, no matter how I tried to adjust the carb mixture and throttle screws, and after turning the choke off just make the revs drop right down then die.
its the kill switch that was stopping it from starting even when it was off, disconnected the black and white wire from the cdi and it started sparking properly
