Ok, I'm getting really frustrated cuz I have been trying to get everything running in ship shape before the season starts, and I just got my peerless transmission back together after having some problems with it. So I FINALLY get it fixed and put back together, roll the mower into the driveway, and pull the pull cord, except....it won't pull! It's frozen, won't turn at all. Now I have NEVER had a problem with this engine, it faithfully starts on the second or third pull, even in the winter. Now its completely frozen. This makes no sense at all because I recently changed the oil. Before I changed the oil, I had run it and it ran fine. Then I drained the oil, and put new oil in it AND I HAVE NOT RUN THE MOTOR SINCE. Now correct me if I'm wrong, but if an engine is going to lock up, it has to be running and not have enough oil in it, causing it to seize up. This is why this makes absolutely no sense to me, because it has not been run since I changed the oil. To my knowledge, motors don't just seize up sitting in the garage. I'm stumped. If anyone has any idea what on earth could be wrong and/or how to fix it, PLEASE let me know! I'm so ready to be done with all this crap and mowing grass again!
