Odd timing problem 360

Another thing I forgot to mention is the timing chain/gears. Even if they are new there could be enough slop to cause erratic timing.

Turn the crank by hand until the rotor moves and then turn the crank the other way until the rotor moves. If you have more than 5 or 6 degrees of free play the chain/gears have to much slop.

Try this in several places plostions of the crank because you can have tight and loose spots on the chain.
