I think the backfiring is just when you manually choke it it gets just a little too much fuel.
If you have...
not in this particular order...
check the spark gap,
check for proper spark,
check the valves,
check compression,
check all electrical connections,
check the FEV,
check for any leaks around the intake manifold or carb to manifold connection,
fuel flow,
cleaned carb thoroughly,
checked carb for proper operations, (everything is there and in working order)
check that the vacuum line is connected and tight.
check tank for proper venting.
(I think that's it, if I've missed anything I'm sure someone will chime in)
If all this is done the engine should start and run properly.
