Default Magnum 46 dies at full throttle.

I have a magnum 46 that is less than 1 year old. It ran just fine up till a few weeks ago, now it runs fine at idle and low speed but dies when I wind it up to full throttle. I checked to make sure everything was tight and there are no air leaks..... I am stumped and was hopping someone out there had some idea of where I could check next. I have been very happy with this engine and would like to get it working properly again. Any ideas would be greatly appreciated. Thanks

It may be too lean?

When the temperature is colder the engine needs to be more lean.

A lean idle can cause the high speed needle to be insensitive

Enjoy,

Jim

Check the spray bar for an obstruction. That is usually what causes this kind of problem.

I agree....it probably has gunk in the carb. Clean it out and install a fuel filter.

as w8ye was saying when its colder you need to richen up the needles just a little bit due to more dense air - also you might try a new glow plug, if no help then try fresh fuel.
