Basically your standard 2 stroke CAG ...

Checked the plug?
checked your gap on the plug or coil?
Are you getting spark?
Is there fuel in it? what ratio?
How old is the bike?
Is the carb clean?
Have you checked the tap to make sure its not blocked?

More info required...

its a brand new gas have no clue

first replace the spark plug to a NGK plug
then if it still wont start look at the fuel system you can test this by pouring 13 of a coke lid of fuel down the spark plug hole put your plug back in & see if it fires
if it fires then cuts out you have a fuel restriction

if it wont fire with a new plug it is probbly a spark problem

you can use the search option at the top of the forum as this question has been covered several times

which kind of ngk

If you have fuel ,spark then it may be the crankcase gaskets are leaking air.As this will make them hard to start or they may not run.
