Default Yamaha 2002 g16 shakes and runs rough

hi all.
I have a cart that runs rough and has lack of power at WOT . I figured it was time for a tune up and carb cleaning , so after i found a new carb was cheaper than a rebuild kit i changed the carb with a brand new one also bought a fuel pump and fuel filter why not right . new air filter and spark plug ..fresh fuel Nothing changed the cart still runs rough and lack of power...Now I'm just confused

Cheap carbs are just that. Cheap, Chinese, and usually crap. It's much better to buy the individual OEM parts and rebuild the original carb.

Check the carb spacer for cracks, and use new gaskets. It takes 3 of them. Make sure that the air box is sealed correctly.

I agree.
Put the original carburetor and fuel pump back on. Sounds like you bought the cheap stuff.

Your problem is probably not that big of a deal and an easy fix.

Guys thank u for ur input .
the cart still has the same problem even after i changed all those parts . starts up idles good but has a sluggish feeling . wide open throttle has limited power and feels like its sputtering . original carb and new one acts the same , i wonder if there is something else causing this
.
