check sync and link...pay particular attention to throttle valve sychronization (make sure they are all opening).
Im assuming it went faster before and noone has changed prop etc.

Dirty or possible gummed up fuel filter? Maybe the check valve in the primer bulb? Can you attach a different portable fuel tank straight to the motor and try it, bypassing any filters and fuel lines you have installed? I always start with fuel and dig dipper from there.

Have you done a proper spark test with a spark tester to see how much of a gap it will jump ??? Which plugs are black and which are the tan color ??

My boat did this a few years ago and I needed a new power pack on one side. I dont know if that is the right terms or part names.
