If your having problem's finding Top Dead center on your engine.
Pull the oil pan
Look at the fist connecting rod on the crank shaft.
you will want to rotate the the engine crank shaft until the connecting rod is all the way up.
This will be TDC.
If you turn the crank to far over the rod will come back down towards you.
rotate the crank until it is all the way up in the engine.
Let me know if i can help more!
