Improper stator orientation can cause a running problem. Weather or not that is your trouble is hard to say… Did you clean and rebuild the carburetors? Replace the inlet needles/seats? How about the fuel pump? If not, they need to be gone through, especially since you have rebuilt the powerhead. I’m sure you know this already, but wanted to throw it out there… A lean running outboard is an open invitation to blowing a powerhead. Remember when fuel flow is obstructed, so is the lubricating oil that’s mixed with the gas.
