you probably need to replace your piston rings or piston, if its a 2 stroke you may have melted the piston and if it is a 4 stroke you may have a valve sticking open. i would pull the head off and check valves, gaskets and piston.
Take it to a mechanic.Your obviously clueless if you think there should be compression between the carb and the cylinders.
Does it have a compression relief valve to ease the kick start? If so, it may be stuck open.
You have internal problems with your engine. I suggest you take it to a shop. You should get the oil leak fixed at the same time.
