i am ready to pull the engine out of a ofna hyper 7 and was just wondering if anybody has any ideas on why the engine could be seized. i am hoping that it is only the pull starter and not internal engine damage. the engine will not pull over and there is nothing visible blocking the flywheel or anything else. i was just wondering what other things could be wrong with the engine or possibly the transmission. help is appreciated.

Pull your back plate off and take a peek in there, sounds like you snapped your conrod.
