What is the volume of a 40 feet sea freight high container ? how about 40 feet normal container ?

I don't know allot about that particular engine, but I'm certain it has more than one carb. Having those carbs in sync is a real big deal. It would most likely require a pro to set properly. Some 150's that are 6 cyl.'s have 6 carbs and some have 3. I'm sure you've done the usual stuff (plugs, etc). Also check fuel pressure, filter, etc. Outboards can be very selfish at times!
