don't know what type of carburetor. spark plug is a champion version of a NGK B6HS. The Champion is a 306 L86C. spark plug gap is between .020 and .025. Fuel mix is 32:1
air cleaner is clean and choke is off
Before I go further I want to take some of your questions and go outside and check my bike. Some of these things I just don't know and will have to look into them. It gives me more things to check.
I will get back with you in a bit.

Is the carb air cleaner clean is the choke off?
checked for air leaks? is the intake manifold gasket blocking the intake?
Did you try an o-ring to seal the carb to the intake which I think is the wrong thing to do is so is it still in place and not sucked into the engine.
your exhaust gasket restricting the port?
head bolts tight?
no leaks around the head or cylinders base?
do you still have the old carb? will it wok any better?
some of the carbs needles are not tapered correctly if at all mic top middle and bottom let me know your reading if you can. Pablo send me his problem child carb that I got to working correctly then sent it back to him.
just some of the things that you can check that might be causing your problem.
