Sounds a bit like timing is out. Check the piston is at top dead centre, through the plug hole, when the timing mark on the flywheel says it is. If it is, check TDC mark on flywheel and camshaft either agree or cam mark is 180 degrees out. If you want to check the fuel tap, take the pipe off at one end and see if fuel runs out with the tap turned on.

How do i pop of black cap to check cam mark. fly wheel is off mark as seen in pic
edit: just realized i didn’t check if piston is tdc. where is the crank? how do i move piston to top dead center? is it the bolt on the flywheel?

Black cap screw out also the center bolt in the cranking bell[recoil] is used to rotate the crankshaft after you remove the black cap look inside you willbe able to see timing marks on flywheel rotate to the T mark[for timing] here in the south we put a drinking straw in spark plug hole to gauge locate piston cycle when TDC both values should be closed an piston at the top an the T mark shouldbe align with arrow inside case and the camshaft sprocket key way and mark on the sprocket should be align with arrow on the head[shown in photo] if the engine has been rotated with the mark like in photo may have bent a value.
