This 390xp pulls 145 on compression and runs pretty good. I did pull the muffler and check the piston, if you can see it in the pictures there are some fine scratch marks on the piston. The cylinder has a couple of broken fins and the plastics are faded. It needs a bolt in the engine cover as one of them is missing, threads are good. Take a look at the pics and feel free to ask any questions. Asking 375.00 for the power head shipped to the lower 48.
