Did you gap your spark plugs before you installed them?

maybe but no missing when it idols or trying to take off... but as soon as you hit to take off it kills , almost like something is restricting the gas flow...like a motor losing prime but the ball is pumped hard...

Have you change the fuel filter.

agree with everyone else...sounds like a fuel problem to me...

clean fuel filter...and be sure the o-ring is ok when you put it back together so it doesn't suck air...

also, notice whether there is water in the fuel filter...

There are drain plugs on bottom of each carb.
Tilt motor up.remove dtain plugs. pump bulb to flush out.
If this doesnt help youll have to remove carbs and clean.

To prevent in future buy some startron fuel treatment and use every time yo get gas.
Yiu probably need to replace all fuel lines from tank ta carb.
Anything before 06 the fuel line will start to break down from the ethenol.

Run some Sea Foam through it before you take it somewhere. Could be water in the gas. I had this happen to my old boat several years ago, ran sea foam through it and the problem went away.

Could be your fuel lines breaking down and gumming up your carbs. If you use fuel with ethenol and have old fuel lines that is what I would check first.:-)

I agree with the lack of fuel but I'd also check all of your power packs and make sure you are getting fire from each wire. . Sounds like all cylinders aren't firing
