Customer Question

Hi. I have a similar problem about the engine stalling out on my Atomic 4 when I accelerate.
I had the mechanic put on a new carb, and we changed the in line fuel filter and gas/water separator.
At start up it needs the choke open more than it used too. After 5 minutes it will idle fine and in general will work with choke closed up to 1/4-1/3 throttle. More than that, it stalls out. Also, if I leave the choke open it will handle up to 1/2 throttle -- more than that it runs rough. This may be too much information. Any ideas?
