What’s wrong with this?

Pulled out of shed after long storage. Wouldn’t start even after replacing and checking for spark, so replaced carb. What is that flame that is shooting out?
Still new to this, thanks for checking out.

update: open to check intake valve and was able to push down on intake valve spring when taking off rocker arm, but when i put the arm back on i notice there was a crack on it and believe that is preventing it from pushing it back down.
