Need everyones opinion on why the radiator is smoking.

That sounds about right, the hoses do get hot and i guess when ive felt the coolant is was hot enough for me to pull my finger out after a second or two. I guess if the engine were to be overheated it would be more scalding than that? Is there a way i can tune my carb? I feel like when its cold i need to open the screws to get it started. and then once its warmed up i need to tighten the 4 screws like half a turn. I usually keep them around 1.5 turns open. However i think my proform carb has a secondary adjuster screw near the choke that i can also turn. Its a bit much for me to fully get it tuned i think. I can hardly even turn the screws because my flat head falls out due to the motor moving so much back and forth usually.

I like what he has been saying, listen.
As to the rough idle and what you describe with the idel screws...try setting all 4 the same, like 3/4 to 1turn out from seated...the secondary blade adjustment wants to be the same as the primary as well which both should just show a crack of the idle slot. You might want to pull the carb and look underneath to see that you get both pri/sec throttle blades adjusted the same. After you bolt the carb on, start it if it will....then if not or if so, set the initial timing as to get the idle rpm around 800ish rpm and note it and get back to us. Wash off that radiator and fans real good. If it will run with the cap off and not spew out once warmed...its not overheating.
