I've got a two stroke strimmer (new last summer). It starts fine and responds smoothly to the throttle but approaching full throttle it cuts out.

I've got a two stroke strimmer (new last summer). It starts fine and responds smoothly to the throttle but approaching full throttle it cuts out.
I've tried changing the fuel for carefully measured fresh mix. The air filter is clean and afaik there is no fuel filter to check. [links]
My barn is fairly open and I wonder whether water has got in, but it strikes me the symptoms are wrong. Also the cylinder can be seen through the exhaust port and at high throttle it glows orange. Is that normal? here
Maybe the kill switch wire has been caught in the throttle cam when the control box was reassembled, this wire may be shorting to earth when the lever is moved to its full extent. It would be easily done, those controls can be awkward to reasemble. You may have to drop it back to the shop more

Mine did that exact thing for a while (seemed to happen most right when a little wave action occured). It was so sudden and complete I was sure it was electrical. Turned out to be water in the carb bowl. carb cleanout, new gas line, new gas tank. never happened since. [links]
Re: Mercury suddenly dies at full throttle. more
-replaced air filter
-replaced spark plug
-Replaced fuel/vacuum lines and fuel filter
-Replaced drive belt for the oil pump and lines
-Cleaned carburator
-brakes, belts, vario rolls, . more
The engine starts with one kick, runs great on idle but when I drive the Vespa it stalls when give it a full throttle. It doesn't do that the first 30sec. when lossen the gas it runs fine again.
I did the following checks: more
-Re-cleaned the carb en checked everything
-Put wd40 on the inlet manifold, cilinder, lines. no change in idle..
-checked the vacuum line
-I see fuel running in the fuel line
-unplugged the choke
-played with the air/fuel mixture

Hello everyone!
I bought a Vespa LX50 2T that needed some attention.
I did a complete teardown, gave it a paint job an reassembled everything, in the meanwhile I did the following engine jobs: more
In this article, we’ll go through different engine parts and the issues that can result in your engine stalling at full throttle. We’ll also point out how to fix the different problems. Let’s begin.
Solution: If only a few parts of the carb are damaged, e.g., the springs, you can replace just those parts. But if the carburetor itself is damaged, you will have to replace the whole thing and rebuild it. [links]
Carburetors mix air and fuel at a precise ratio for the combustion process. Anything that prevents the proper airflow or entry of fuel will result in the inefficiency of the carburetor. This can lead to the symptom of your two-stroke engine dying at full throttle.
Solution: The only solution to dirt accumulation is cleaning up of the carburetor. A carburetor cleaner will do the job. here
To know if the problem is clogging, lift the covers to the carburetor and remove the air cleaner cap and filter. Carefully check for any obstructions. here
There are a few common problems that can be encountered with a carb. Let’s have a look at some of them and their solutions. more
Solution: Identify the adjustment screws and adjust the carburetor until the air/fuel ratio is well balanced.
A good assessment of these different parts of your engine can help you find the culprit and replace it or fix its problem.
