Here Is good tip a old timer tought me. and it works evertime. take the timing pin out and turn it around and and put it back in. now take a c clamp and put on the timeing pin and the timing cover and tighting it up to where it is snug. now pull the # 1 plug and turn the motor over when you reach TDC the clamp will fall off. look in the spark plug hole making sure you are at TDC. hope it helps.
