just refuse to start

[jsbulat]

Hi,
Could you please help me?

My GZ250 just refuse to start.
Usually it was starting very easy, but once it stall on the stop sign when i release the clutch at wrong shift. After that it not even "sneeze" when trying to start. Battery is fully charged and ive checked the spark-it's ok.

Is this known issue and what can you recommend?

Thank you.

PS. 1) Does not start whether i use choke or not.
2) Battery is good, spark looks good. Turns very good.
3) There is a lot gasoline in air filter chamber (probably because of desperate cranking).
