Yes firing order is correct

Here's a few things I can think of , the actual timing and weather the distributor is in correct. Confirm the engine is on top dead center on cylinder #1. Pull the plug and put your thumb over the hole and have someone bump the engine. Watch the timing mark on the balancer when it gets to 0 degrees , if its blow your thumb out of the hole it's at TDC if not it's still 180 degree's off. If your sure it's at TDC and the harmonic balancer is pointing to 0 the rotor inside the distributor cap should be pointing exactaly at #1 plug wire or you should be able to turn the distributor to that spot. If you can't you will need to pull the distributor and re-install. Sorry if your beyond this part but it sounds like your issue. If the engine timing is off you can usually turn up or down to make run. Only other thing I can think of is a big vacuum leak from the carberator . Good luck
