Baotian BT49QT-7 not starting

[bean1971]

I have a Baotian BT49QT-7 scooter, nothing changed/upgrated with 1230 km run on it with a problem.

Engine stopped all of a sudden, did run just fine.
Checked the spark plug, no problems with that,.it sparks but when i screw it back in the engine just will not fire.
There is fuel flow to the engine.
Tried both electric start and kickstart, no result

Any ideas what to check?

Thanks

if its turning over then check valve clearences

Could it really be that? What i mean is that it was running perfectly, it was turned off,..and tried starting 2 minutes later,....and then it did not start anymore.

yeah it could be, quite likely

[bean1971]

All right, i'll take it to the shop to get that done then,..too much hassle for me

Thanks

Double check the side stand switch. Could be that
