I had the flywheel off to install the Koso cam chain tensioner. I’ve had it back on twice now torqued to 47lbs per the manual but the first time it slipped after turning the engine over. I just took it back off again and it was REALLY easy to loosen the nut holding it in place. Evidently I’m doing something wrong here. A little help would be appreciated. Had to replace the woodruff key from the flywheel spinning loose I guess ?
