Motor Stalling

[KeithsT1000a]

I have a BAJA 5T with 34cc motor with 990 carb and Bartlone side pipe . After priming carb and a couple slow pulls on starter rope to prime engine, engine starts right up and idles. I can start motor on stand and let idle, and rev to high RPM's an all is good. When I put on the ground to run and she will take off and I will get into power band and out and it will stall, also sometimes when it stalls it cackles just before it stalls, any ideas.

Your running out of fuel, would be my guess. Bad fuel pump or something like that what engine is it? Zen, km or what ever

Motor is KM and I did a search on here and read where maybe low battery voltage might be an issue, I was going to check that. I just upgraded the carb about a month ago and installed the spiral wound diaphragm, but you are on same track as I, it does act like it runs out of fuel.

Yellow on bottom and Black on top.

Black is usually the feed and should be on bottom. Return is usually clear and is on top.
