Triple Mikuni Burble/Stutter

Recently replaced my fuel system on 70 240z.

 

Started it back up last night after a few months of been idle.

 

Started up a little lackluster but nothing uncommon. After two minutes of rough idle the carbs started to stutter or burble. I'm adding links to the youtube clips I took.

 

I didn't run the engine for much longer just incase.

 

Fuel system: tank - filter - pump - regulator - manifold - carb - carb - carb.

 

Any thoughts?

I'm assuming no return? Some people advocate putting the regulator AFTER the carbs. I run my system with a return, and my regulator is after the carbs (3.25 psi). Tank - filter - fuel pump - carb carb carb - regulator - filter - return to tank.

 

Anyways, after watching the video, its kinda hard to determine what/where that noise is...have you taken off the air filters yet? Might make it easier to determine which throat is making the most noise. Any fuel leaking out the horns? When was the last time you checked floats and synch'd the carbs?
