Mini chopper wont start?

I havent ran my mini bike in about a year. Now when i try and start it it wont start. I cleaned the carbs, replaced the gas and oil, and replaced the spark plug. What else could possibly be wrong? Please and thanks!

i did all that stuff and it still wont run. it seems like its trying to start better though.

Did you check to see if the battery was still good? May need charged or need a new one. Did you set the spark plug gap?
When you cleaned the carb did you remove the jets and clean the little holes in the jets? Did you clean the air filter?

The engine needs 3 things to run. Air, Fuel, Spark.
When you tried to start it did you check for spark? When it didn't start did you remove the plug to see if it was wet with gas? Did you put the carb back together exactly as it was?
Just a few things to think about.

Congratulations! Now you know a little more about making your bike run. Way to go! Report It

check what everone wrote and check your cdi box or your coil.

if its turning over but has no spark try new plug first if not

cdi ,coil, or stator

What kind is it?? even they have diffrent models

get some starting fluid from home depot or ur local auto parts store and then give it a little squirt right into the carb opening with the choke off and if is starts and then wants to die give it another little squirt and continue until it runs off its own fuel.
