White smoke or light blue actually is oil. If the car was burning raw fuel it would be black. You issue is probably bad rings. That could explain the white smoke, and if you pump the gas 100 times before she starts, its likely that gas is going righ past the rings an into the oil. How old is the motor? Has it been sitting long?
A good trick is to take the plugs out, load each cylendar with WD40 and let it sit for an hour or so, then hit it again, wiggling the red tube all around the plug hole (making sure the wd40 is getting into the cylendars) then with the plugs out, (and the coil disconnected) spin the motor over for about 30 seconds to a minute. THis will help reseat the pistons, and also help clean some of the sh1t of the tops.
THEN change the oil, put new plugs in and let er go. Some people will probably cringe at this method, but i'ts worked a few times for me on old engines. About starting, pump the carb 3 times and hold the pedal open. Also, you might be loosing the fuel out of the float boals somewhere so it might take spinning the engine over a bunch of times till it fills up, (might explain) the numerous pumpings also, but with an electric fuel pump, that wouldn't be the problem, just let it run for a second or two before firing the car up.
Let me know if this helps, also, you might check timing, hard starting motors often have too advanced or not enough timing which causes them to need a ton of gas before they fire.
