Random power on suzuki 115hp 1986

[allanfraser]

My 115hp suzuki engine starts perfect, idles fine, but after about 5-10 minutes while running at full throttle, the engine cuts back to between 60-70%. The power returns at random and then runs for a short time before cutting back again. This problem is random and there is no routine to it. All carbs have bee n cleaned, new plugs fitted, good sparks, everything seems to check out fine.

Try choking it when it acts up and see what effect that has. If it improves even a little it would point to a fuel problem. If not maybe you've got gremlins in the ignition. Also is the fuel bulb collapsing during these episodes and does pumping it by hand have any effect.

I just had the exact same problem with my 1986 115 Suzuki. We thought it might be fuel related, but found out it was in the power pack. From what I'm told,it is the brains of the operation. I was surprised at how many intricate things the power pack controls. Hopefully it's not your problem. Maybe it's just a coil?
