check your timing and make it correct, if thats the problem itll be an easy fix!
i am in the process of trying to fix the timing and i am pretty sure its the head though because on small displacement motors timing doesnt affect much unless it is 180 degrees retarded or something

do you have a timing gun? if you don't then you'll never know. ive been trying to fix a problem ive been having and when adjusting the dizzy timing and driving it felt like night and day.

edit: its better to work on all the small parts first before needing to take the head

well the springs are supposed to require 80 ft pounds of torque to press them down and mine are like pressing an ink pen so they just like bounce

How do you know valves are floating, springs feel weak?? Did you press down everyone. Try putting it to tdc and try pushing on everyone. I don't think all your springs would go at one time.
