so i just recently pulled my mower out of storage for the season, changed the oil and put gas in it and discovered the primer bulb didn't work so i used starting fluid and it started right up no problems runs as it should cut front and back grass. next week pulled the intake and primer bulb piece off and the gasket was shot, used gasket maker and waited till the next day and priming works so i started it up to cut and ran great but about halfway through i noticed a slight ticking but didn't think much of it b/c i was almost finished. after i finished i emptied the bag and went out to the front yard and when i went to pull the engine over something was really wrong, pulling the engine over it was like the conrod had shattered but the engine was still turning over and each revolution it got worse so i called it and tore the entire engine down to the crank case and the conrod screws were totally loose and figured this might be an easy fix so i gutted the engine tightened the conrod screws to 95 footpounds and the engine was totally locked up, tired putting out on it but still seized so i took the piston and conrod out and they are pretty badly scored after reassembling making sure the conrod isnt angled and everything is lubricated but when tightened the conrod seizes against the crankshaft. loose and everything spins fine. What went wrong here. was there not enough oil and got too hot? if so wouldn't scoring the conrod and crankshaft make it looser instaed of swollen and tighter? Are all i need is a conrod and maybe crankshaft? the piston looked fine just alot of carbon buildup.
