Sounds like a fuel problem .. more throttle engine needs more fuel . Also check timing , little or no advance can have the same effect. I would start there .

Re: WOT stalling

I agree with a fuel problem. My honda carburetor book states that the most likely cause for this symptom is restricted or plugged main jet(s). Since you have 4 carbs, i'd advise a overhaul/rebuild of all of them to ensure you get the faulty one(s). Then a synchronization of all 4 is required to ensure they equally share the load throughout all speed ranges.

Hope this helps.

Re: WOT stalling

to synchroniz the carbs i need the set of vacume gauges corect? if so any idea where to get them?

Re: WOT stalling

You might ask your local marine dealer or Honda dealer. I've heard of others using motorcycle vacuum gages, but don't know how well or if they worked.
