Bought an 038 Mag II and gave it a good once over. Pulled the muffler to check it out, no scoring on the piston and cylinder= good news. Checked compression and was just over 150#. Chain break handle missing= bad news - of course it was missing the whole chain break assembly. Luckily I had a parts 038 and was able to simply swap everything over. I decided to try an 8 pin sprocket also - seems to have plenty of power to pull with it...
