The advance is purely mechanical...no vacuum diaphragm on a jeep.

To check the timing, you can replace the number one shielded spark plug wire with a normal 7mm or even an 8mm wire with both ends square cut. On that you can use a normal inductive timing light, with only one battery hooked to the power leads (12 volt or you will burn out your light). If you have one of the fancy lights, you can retard your timing on the light by 30 degrees or so, rev up the jeep motor to 2000 rpm, and see if the mark on the pulley goes back to zero.

To check the weights, it's easy enough. Remove the distributor cap, and try and turn the rotor. It should rotate (about 30°) and then spring back to where it came from. You should occasionally oil the wights pivot pin....remove the points plate and the weights are underneath.

To adjust the timing, you loosen the bolt at the block, and turn the distributor.

Popping on acceleration can also be stale gasoline or else spark plugs that are over gapped (30 thou is the correct gap).
