How do you set the timing on an allis chalmers 649 engine?

Answer 1

To set the timing on an Allis Chalmers 649 engine, first ensure the engine is at Top Dead Center (TDC) on the compression stroke for the number one cylinder. Next, locate the timing marks on the harmonic balancer and the timing cover, aligning them as specified in the service manual for the correct timing degree. Adjust the distributor by loosening its hold-down bolt and rotating it to achieve the desired timing, then tighten the bolt once the timing is set. Finally, verify the timing with a timing light at the specified RPM.
