I need some help, info on why the engine of my machine is flooding right away. When I pull it over a few times I can smell the gas, plugs get soaked and I can see some gas dripping from exhaust. wasn't working properly before so i did a rebuild on the carb - now this, what did I do wrong?

Check your inlet tip for wear ,like a round spot at the tip.Also the inlet lever must be flush with the lever body area.Could be also small particles,dirt,etc at the needle keeping it opened and letting the gas go tru.Blow air the carb .

this is a tillston carb right?

It sure is.
