People 50 2t dies at wot

[Crappykymco]

Seems my last thread kinda died so ill start a new one now that im better educated and have a lot more information. The symptom is that my moped will idle fine, rev fine, but if held at wot for any length of time it eventually sputters out and will either go back to idle or just die.

Tested items:
-Fuel filter
-petcock
-ignition system
-carb jets (cleaned)
-carb float (cleaned port and bowl)

As the bike starts to die out after a wot run i can hold my fingers over the carb inlet and keep it running. So its definitely not get the kind of fuel feed it needs. Ive applied vacuum to the petcock without running and fuel flows. Ive run the bike with out a fuel filter and there is no change. Is there some mesh in the tank or something that may need cleaning?

What's the spark plug color?

When you say you tested the carburetor float, did you check the level? Too low and the bowl will run out of fuel with high demand.

 Spark plug was fairly clean with a slight tan-ish color, from what ive seen the spark plug color seemed to align with a running lean condition ive been expiriencing. How do i adjust the float or check the level. All i did was clean the inlet to make sure there was no debris or that the rubber cone hadnt popped off and stuck in there.

There's a bit about it in the service manual at 11-10. Oddly, it says that you need to replace the float if it's out of spec, but usually there's just something you need to bend.

"Notice carb pukes fuel."  What does this mean?

"Ive applied vacuum to the petcock without running and fuel flows."  Yes, it opens and closes but we don't know if it opens enough.
