Bought a motor..suppose to run good., rolls over like it is hot and the timing is out... has a dead spot.. you can turn the engine over til almost top dead center and then you can put a pipe on a ratchet and it won't budge... bump the starter and it rolls to the exact same spot like if it was
50 below.. I haven't touched the timing.. and it does the same thing with the plugs out.. (just not aas bad). Flywheel is turning fine and is not warped. It is a l99 lt1 based motor. SBC 4.3 v8 (not a six 8 plugs) People are saying valves are sticking due to it sitting a while, others say it is cold out and it sitting can cause it, others say battery and starter are weak.. BUT this shouldn't affect it turning the crank by ratchet. Any input would be great.- posted
