'86 150hp stalls at full throttle

[rayrraff]

I was at the lake today and my 150hp was running like a champ. Then suddenly there was a loss of power. I took her off the plane and tried to re-plane but as soon as I would punch the throttle she would stall out.

At low RPMs she runs fine and when shes in choke she runs at full power as well.

Anyone got any ideas?

Clean the carbs.

Try constanly priming the fuel hose bulb. This forces extra fuel into the carbs. If it runs when priming, you may have a weak fuel pump.
