Having throttle problem with 03 2 stroke engine. Engine has stalling problem when pushing throttle from 1500rpm to 2000. I have push it up real slow or it stalls. If I get it past 2000 rpm she engine runs great. Since the problem started I changed all 3 carbs and fuel pump. Still not working.Send to shop and they couldn't figure it out. Any help would be great. Thanks
