Poulan BVM200VS blower / vac wont start

I am at my wits end.
This is the BVM200VS model. About 9 years old. Just replaced carb, plug, fuel filter, fuel lines, fuel. It will only start on full choke and will run about 10 seconds, then die. I notice when pushing in the fuel primer, it stays in, then very slowly pops out. In order to prime bulb 3x, it takes about 4-5 minutes. Have removed muffler and that is quite clear. I am ready to toss it and buy electric. I have tried putting the old primer bulb on the new carb, and this will pop out quick, but still will not prime properly. I feel that this could be the root of the problem, yet I have no idea why. The fuel filter is new. I have even tried priming without the filter and still it will only run about 5-10 seconds, with no throttle response and only on full choke.

Did you by some chance get the fuel lines crossed,I believe you should be pulling fuel through the carb and back into the tank.

They are correct

Mixed with the air bubbles is fuel, going back into the tank. I am thinking 3 possibilities:
1. fuel inlet line is split someplace.
2. problem with new primer as it does not quickly pop back out.
3. air leak someplace in the carb (yet it is new last week).

Sounds like the screen inside the carb is clogged. Did you put this carb on before the fuel lines and try it?

tried it before

I actually tried the primer before putting the fuel lines on as I wanted to make sure I had them correct. I could def feel a bit of suction on the inlet.
