    My Honda GX35, not quite 2 years old and has less than 10 hours running time on it will not run at full throttle. It starts fine and idles as it should. Will run at idle all day long, but when I give it full throttle, it just dies, just as if I had pressed the kill switch. Plug looks good, air filter is clean. Anyone got any bright ideas or know anything about these engines. I bought this engine new from Tewarehouse. It came with no instructions or owners manual, and I admit I have not researched it on line yet. First thing that went through my mind was high speed adjustment, but there seems to be no adjustment screws on the carb. But as I said, I have not done any research yet. This just happened this afternoon. Any and all help will be greatly appreciated. Thanks !

    Had that on a 25. Needed a new diaphragm in the carb. Whole new carb was just 10 bucks more, so I went with that.

    First thing I would think of is the carb, perhaps the jet is blocked or fuel has gummed it up and it is getting to much air versus fuel at WOT?
