Kt100 carburetor not spitting fuel Into the engine

[Sushi]

Hello

So me and my Dad have been working on this kart since spring this year and we need help

Just like I’ve said in the title we have a kt100 engine and the problem with it is the carburetor isn’t sucking fuel and spitting into the engine

we have checked the fuel lines, and fuel tank and fuel is able to go through but the problem is it’s not being spit into the engine via carburetor we have recently replaced the carburetor with a full built carb that is supposedly for juniors but fuel still isn’t going through. We are confused and need help

we put fuel into the fuel line that goes from the carburetor to engine. the drill into the clutch nut and try and started the engine fired but didn’t keep going. Full video here:https://youtube.com/shorts/l9ae3ETSyzQ?si=jy4LWHId_SDIWhI_

Please help us

I’ve got to bow out of this one.

I am assuming from your picture that it is a 2 stroke. Does the engine use a reed valve chamber. Don't know if chamber is the right word, but a lot of 2 cycle engines have a reed valve chamber or set-up between the carburetor and
the intake port on the cylinder barrel. I don't see one on yours. Is it supposed to have one.

If it does have reed valves make sure they are not broken.
