    1974 aircooled engine DOES NOT have a timing chain or belt.

    Driven by gears on the crank and camshaft.

    Static timing is set and set with strobe after.

    I have since sorted the problem from a diffrent forum.

Could a fuel filter in vw 1600 beetle cause backfire

very unlikely
back firing is from partially open inlet valves , incorrect firing order , shorting across the points , faulty condenser , loose coil wires or faulty pigtail wire from the points plate to the ground ( distributor body)
seeing as to you have put in new points , I suspect that the condenser lead is shorting across to the points plate where it attaches to the moving point spring
also if the firing order is wrong after replacing the distributor cap that will also cause the problem

How to Check the Compression on an Aircooled Volkswagen (Vw) Beetle?

Pull all the spark plugs and crank the engine over equal times for each cylinder, 3 or 4 complete revolutions will do. All the readings need to be no more than 5% different from the cylinder with the highest pressure.

No. Check if it is the head gasket or simply the rocker cover gasket that is leaking. The cylinder heads can be removed with the engine in place, if it is the head gasket.

1996 Pont Grand Prix ---- P0303 again & again

The Specific code "P0303" is stating that the Third Cylinder or Cylinder number 3 Is mis-firing, thanks to all that you have done this has narrowed it down to two "confirmed" possible problems;

The first is that the Exhaust VALVE itself may be "Burned" and the Second may be a Poor condition or "Faulty" Catalytic converter(s).

This is only a possible cause but please keep in mind that on some certain models (not too sure about this specific model) there are multiple O2 Sensors located in different spots. (usually in or next to the preliminary and primary catalytic converts)

Also one of my experiences lead me to beleive that the Ignition Control Module (ICM) may be faulty causing the injector to not provide proper Fuel to the Cylinder.which will more often than not cause the computer chip to sense the misfiring as opposed to the bad signal from the ICM.

Hope it helps you out, and good luck.
