Couple of things , Just start the engine and let it Idle , I have put cams in engines w/300 hours , I have run them out also .... A galled cam will not stop an engine , and all cams don't gall from sitting , Start it up , run it to temp for 30 minutes or so , change the oil , look for metal in the filter or screen....If no metal , fly it for 10 hours and then change the oil and filter again , check it for metal , and if no metal , Fly the crap out of it....... Av gas can sit for 10 years and still be good , I have burned a lot of old fuel in my runners , if you are that worried , top it off before you ferry it , Don't listen to all the "experts" if it has low time on the motor , you can IRAN it with new cam, followers , bearings gaskets for about 10K and fly it another 2K hours.... If you haven't already acquired the MX170 , the Kings are better radios , just archaic to tune... Get a local A&P you trust , and put your trust in him , and don't second guess him....
