Just got the 52 DC inside after it had been sitting out for a few months, it was supposed to be stuck when I bought it but last weekend I had a chance to tinker with it a little bit, pulled the valve cover and checked all the valves, all were loose. Then I pulled the hand hole covers off, pulled the plugs out and squirted some penetrating oil in the cylinders and after about 30 minutes I noticed oil leaking into the pan around the rings so I tried the hand crank but it wouldnt budge. After further inspection turns out the shaft that the crank goes in wasnt even engaged in the crank pulley, it was rusted solid so after I got it freed up I grabbed the crank and gave it a turn and the engine rolled right over, I"m gonna pull the carb off and clean it up, get some plugs and a set of plug wires and see if it will fire up. Is there anything else I need to check before I try to start it for the first time in many years? Sorry for the long post
