If its a quick stall, as in a sneeze then dead, either the timing is off or its running lean. If it just dies off more gradually then its a fuel delivery issue.
Running in a drum is hard to calibrate these motors due to exhaust ingestion. Use a shop fan to blow fresh air on it to rule it out.
You can try turning the mixture setting up; or put the cover back on. They run lean with the covers off and will do just what you describe when trying to calibrate in that scenario.
Usually once calibrated in my 300-gallon test tank, when I put the cover on the mixture setting has to be turned leaner by a 1/4 – 1/2 turn otherwise it dies off at low idle/blubbers out.
Dont rule out a speck of dirt in your low speed orifice/jet. Those 2-3 little holes in the venturi can get clogged easily. Ive used a piece of fine wire to poke those holes and then the motor runs perfect. Theyre very sensitive.
