Sounds like the two stroke oil pump is passing, may need repairing or replacing but one thing is for sure, if you pull off the oil pipe from the carb and leave it overnight in a container, there should be no oil seepage into the container because there is a check valve in these pumps that will stop this free flowing, also check the operation of the pulley against throttle position. The over enthusiastic oil delivery will have an adverse affect on performance.
