just run through it methodically. engine only needs fuel + air, and spark (at the right time) and compression

it sounds to me like the timing is out so double check your timing marks, plug leads are going to the right plug.,


see how it turns over and then kicks back a bit, try retarding the distributor a little. maybe its out 180 degrees



some basic tests you can do in general when an engine wont start are

pull the plugs and visually inspect them while turning the engine over, you should see them all sparking if so ign is good*
put the plugs back in and spray some starting fluid down the intake
if it starts right up on the ether then you probably have a fuel delivery problem (carb jets blocked, float stuck, fuel pump issue, injectors not working)
if it chuffs and backfires and kicks back then there is probably a timing issue

compression is a bit harder to test with no tools, but you will notice it sounds funny when turning it over as the engine turns easier on the bad cylinder
