Check your gaskets and vacuum ports on carb sounds like a vacuum leak mine I can make it idle close to 600 rpms. Make sure the carb to intake gasket is good

sprayed throtlle body cleaner (extremely flammable) while running no change in rpms, so i would say gaskets are good i can change timing and have it idle lower

It sounds like you used the markings on the pulley, which are used to set timing at idle. However you did it, you got it to work now.
