Having real hard time with Carb.

Try replacing the fuel petcock diaphragm. Get a rebuild kit for about 18 bucks. Its very easy to do and can eliminate a fuel delivery problem you may be overlooking. There is a vacuum line that goes to it so check that its in good shape and not deteriorated to the point of leaking not giving that diaphragm the vacuum it needs.

Having to run with the choke on usually means you aren't getting enough fuel the normal way it should. with everything you checked already it does sound like a fuel delivery problem not valves or head gaskets. At least that's my 2 cents worth.

Good luck and keep us posted!
