Pull the slide out of the carb then remove the jet needle and move the clip one notch lower on the needle.

Quitting is a no-no. Move the needle clip down one notch and also remove and clean the carb if it has been dieing..

My 'wing won't run unless it has been warmed up some. I would suggest that you r&r your carbs to make sure the jets in the bottom are working correctly. They tend to get plugged up, especially after sitting & the aluminum flaking off inside... Rick

fuel carburetor problem! it causes most of the spluttering problems i have encountered with mine so far!
it could have blockage and insufficient gas enters on it during high revs!

There seems to be low gas level in the float chamber of the carburator.
Clean the carburator and check the float level and reset.
With the choke 'on' and if you hit the throttle it will die because there is a restriction of the air flow to the carburator.
