My eldest grandson just bought his first home and informed me he needs a mower for his not too large yard. I remembered seeing a new looking Poulan mower sitting beside the building w/ all the unused display racks at our local Alco store. I gave it a pull and it had compression, so asked the mgr what the story was on it. He said it was returned because it seized up and if I wanted it take it. I had noticed oil on the deck under the muffler and thought that was sorta good news or really bad news. Got it home and removed the air filter and found the outer holes filled w/ a mixture of oil and dust. Removed the plug and it had oil on it but still sparked. Checked the oil and it wasn't touching the stick so added oil. Took it outside , poured a little gas down the carb and it started on the 3rd pull and ran 'til the gas was gone. Tank was empty, filled it half full and poured a little more down the carb and it started first pull and died. Hit the primer bulb three times and saw it squirt gas, pulled, it started and died. Tried this 3 more times w/ the same result. Took the carb off and found the main jet reservoir was full of oil. Cleaned it out and reassembled. Had to drop it and make a run to Pocatello w/ the wife I'll finish up w/ it tomorrow and I think it's going to be fine. It appears to me the PO had it on it's side w/ the carb side down and it filled the cyl w/ oil causing hydrolock. After sitting for several months the oil leaked out of the cyl. If it runs OK I'll let it run about 15 min at WOT and then check the oil to see if it's making any metal. So w/ a little luck my grandkid gets a free mower.
