hpw does the cylinder liner look, is it scratched??

if the liner is not scratched bad start over. check for fuel blockage, clean the engine, if It was my engine I would close the needle and open it 2 turns and start it.

I do not understand why the manual says to open the needle so much. I am wondering if your manual is for an ABC engine, not a ringed engine ??

I hope you don't over tighten the needle when closing it.
