I'm sure you have one of the wires crossed or your distributor is in 180 degresse backwards

  • sound like you have it timed on the exhaust and not the compression - or 180 degrees off. Get it to TDC, rotor on the #1 plug wire, and go from there.

You are bad out of time, or maybe you have wired the wires in the wrong rotation. It should be clockwise rotation. Check to see if you have wired it correctly, also if you have removed the distributor and reinstalled it you may be out of time.

Backfiring generally indicates a timing problem.

It could be as simple as a cracked distributor cap allowing the spark to jump across the moisture. Or it could be more serious.

The popping sound is backfiring this occurs for a few reasons one reason is your vehicle is running to rich or to lean this happens when you don't have the proper fuel and air mixture you can adjust this with a screw on the side of the carburetor.
