I believe it may have sat for 5 years. after a lot of work i removed the cobra outdrive. I removed all the spark plugs. i hotwired the starter and only here a "clang" which i read somewhere means the engine may be seized. people then say use a breaker bar to try to turn the engine over. i have no idea where to attach a break bar to. I took my socket wrench to the harmonic balancer and just ended up removing the bolt. how do i crank it over manually by hand, how do i know its seized, what should i do now?
