New Carb on Tecumseh 8hp Snow King - Runs Full Choke Only

Pretty much like the title states. New carb and new fuel line. New primer bulb fuel line as well. When I prime it I'm thinking I hear it suck a bit of air. Can't recall if I've heard this before because the machine always ran great until I found the leaking primer lime.

Only runs on full choke. Newer style carb with 1/2" bolt on bottom of bowl. No adjustment pin on bottom of bowl. Played around with mix screw on side of carb body with no luck. Begins to stall when I take it off full choke. Thinking I'm not getting fuel to carb but as mentioned, I replaced everything. Don't think I crimped the main fuel line when I replaced the old one.

check the float level even on a brand new carb its best to pull the bowl and check the float etc before installing it
much easier off the machine then on

The screw on the side is non-adjustable, it's a jet, needs to be tighten, not a mixture screw.

Spray some starting fluid at the intake gasket, maybe a leak there. Otherwise follow the advice above. Defective carb? Somehow dirt in one of the holes?

Remove the fuel bowl, see how fast fuel is leaking out.
