Trimmer is flooding.

It appears that the carb is not functioning properly. Sounds like the needle is not seating properly. It will need cleaning or repair.

When pumping the fuel bulb, is that to build up pressure in the fuel tank?

Its to make sure you have gas going into the carburetor. That helps it to start easier. Don't over do it you can flood it out

I can't get it started and I"m following directions on side of machine.

Those direction are not accurate all the time, I usually prime mine 4-6 times. put mine on full choke with the trigger pressed and pull 1 time any more will usually flood it, If you have the choke that kicks off after you press the trigger, put the choke back on to half and pull the cord pressing the trigger, Then pull the cord until it starts without pressing the trigger. As before if you press and hold the trigger during the start it will flood these trimmers..This should start the trimmer. You may have to let the trimmer set for about 15 min if it was flooded.

When i start it up and let it run for the 30-60 seconds then squeeze throttle it doesn't want to run. almost like it either starves or floods.

Definitely sounds like a fuel delivery issue. It may be time to install a diaghram kit or rebuild kit on the carb. The sensitive internal parts don't last forever. You can check for flooding immediately after by pulling the plug. If it is real wet, either the plug isn't firing to its full potential or the carb is indeed flooding.Those carb kits aren't too hard to install and you may be able to get by with just the cheaper diaghram kit.

Following replacement of a broken pull cord the Zama carburettor floods when the tank is filled. The carb does not flood when the bare essential amount of fuel is used, and the engine only fires-up when...

The tank vent is plugged and pressure is causing the unit to run badly, there should be a filter looking thing mounted higher than the tank but attached to it, clean, repair or replace it.

Trimmers floods its self, will not stay running

It is unusual for a trimmer to flood itself. It is common to have a lean condition diagnosed as rich.
So lets start by seeing if its lean or rich. Get unit running and apply as much throttle as possible and keep unit running then slowly close the choke. If unit starts to run better as choke is closed then it is lean. If unit dies immediately and is hard to start again it may be flooded.
4 possible reasons for flooding...
1. piece of debris in inlet needle, needle lever adjusted too high
2. adjustment screwd turned too far out
3. exhaust screen clogged
4. low compression
If unit has a stuck inlet needle it will flood while engine is off and be very difficult to start- remove fuel source and/or turn adjustment screws all the way in and pull rope until unit starts ( 4 or 5 times)
clean the carb, screws should start at 1 and 1/2 turns out on the low and 1 turn out on the high.
clean the screen.
If the unit has low compression it is not worth repairing- the cost of repair will exceed the cost of replacement.

Trimmer dies when you apply throttle

Sounds like it might be getting to much gas. What position is the choke in during all of this? If you're giving it throttle it may be flooding itself out.
