I'm going to crank the motor. It sounds like it's hitting something like it's binding up, but if I disconnect the distributor like remove the coil wire it runs fine. Hook up the coil wire and it goes back to that knock and grab. So, I'm assuming it's the timing because I checked the firing order and it's fine. So, how do I adjust the timing, I do have a timing light?

The timing is not adjustable in this engine. Please check it out what I found:

Base Timing
The distributor ignition system has no provision for timing adjustment. The base timing is preset when the engine is manufactured, and no adjustment is possible.

The distributor may need adjusting to prevent crossfire.

Did the engine run before or is this a new set up? Please go over how to install the distributor correctly. Check out the images (below). Please let us know what happens.
