You have some seriously mismatched parts, and it's unlikely things will get any better until those problems are corrected. Chasing one's tail trying to make a wrong carburetor work can be very frustrating, no matter how much money has already been wasted. It seems you've got some incompatible valve train bits and pieces, also. It seems that you're determined to ignore everyone's well-intentioned advice and press on with Band-Aid fixes. Good luck!
