Maybe the engine was running well because the piston to cylinder sleeve seal was good from old oil. You cleaning the piston and sleeve may have reduce the compression. Check the idle screw adjustment first and hopefully you can get the idle back. Otherwise compression is the biggest issue regarding a poor idle.
