It could be timing is off. Need more info. Is it Fuel injected or Carburated? Exhaust smoke? Is it black? Black indicates alot of carbon built up. May mean the fuel is burning way to rich.

What would cause a 1979 VW Beetle to backfire?
There are two things that can cause it. The most likely one is timing too retarded. The other is an exhaust leak. Since your car is fuel injected, you probably have the Exhaust Gas Recirculation system hooked up, and this is where most of the backfire-causing exhaust leaks come from. So it's probably timing.

Why does a car backfire?
A car backfires because unburned fuel is getting to the muffler. The heat of the exhause system causes the fuel to combust, thus a backfire.

A fuel line and an oxidizer line are added to the muffler with a manual rubber bulb pump added to the line as the ''backfire button.'' At a point before entering the muffler, the lines have a pair of backflow valves to prevent the flame from racing into the mixture tanks. Squeezing the bulbs dispense a mixture of pure alcohol and an oxidizer into the muffler to create a reaction. For Onslow's car in the TV programme, copier toner was squirted in the tailpipe for a heavy soot effect on the backfire command. Having a car backfire can shake off any parts that aren't bolted completely, and can cause the engine to stall because the pressure of the backfire can temporarily disrupt the exhaust release from the engine. Besides, it would spook horses, cows, or anyone not used to loud noises. So having the car backfire down a Harlem road won't have the same effect, as a car backfiring down a rural city road.
