Move the coil signal wire from the trailing to the leading coil and see if that
helps your tach.
With all the backfiring you either have a spark issue or a fuel issue or both.
If you can rule out the spark then you can work on the fuel. Kind of hard to
deal with a fuel issue tho ift he spark is unknown quantity.
