It should be possible to test the pump for proper function - there should be no need to replace it hoping for a cure.

A fuel pump should suck at one end and blow at the other and this can be measured using appropriate gauges and if those measurements are satisfactory the amount of fuel pumped can be measured...

Such tests are fairly routine on wheeled vehicles and not only are they a valuable aid to correct diagnosis they remove all doubt when warranty work is involved.

The only way it will run backwards is the timing is incorrect. If you had the flywheel or anything in the engine apart relating to the ignition pickup coils, they didnt get put back in correctly.
It's possible something is loose, and sheared the flywheel key. 2 cycle will run regardless of direction due to no valves.
