Try to suck some fuel to the front from the reservoir and then try throw some directly in the carb. This should make the pump going Wink


working after a good suck Wink

The fuel can not be getting to the cylinders. Is there fuel in the float chamber?

Has the car not been used for a while? Perhaps the needle valve in the carb is stuck shut?

Need to know what carb it is really but on most you remove the top cover, the chamber should contain fuel.

If your accelerator pump is delivering fuel you've got fuel in the float bowl. If it won't fire when turning over and pumping the accelerator, it's either flooded, (plenty of fuel) or you've got a spark/timing problem. In which case it should still cough and fart if the timing's anywhere near where it should be.

It's rather common it seems to get the timing 180 degrees out (I certainly fell for that one  Embarrassed). With the timing marks aligned it is number 4 cylinder at TDC and ready to fire and not number 1 as most assume. So double check the ignition timing by setting up the camshaft/crankshaft marks and removing the distributor cap to verify that the rotor arm is pointing at number 4 cylinder position.

firing order is 1,3,4 and 2   ,,,,,,,  isnt  (2 )  actually cylinder 4  so rotor arm should point at the third cap on the dissy ?? does this make sense

With the crank at TDC and the cam pointers lined up, whichever pin the rotor button is pointing at should have the lead from number 4 cylinder on it!

Yes and number 4 cylinder is the one nearest the bulkhead.
