I'm ready to give up on 3w ,Its been sent off 4 times and it just sucks,brand new.Wide open throttle it runs like a bandit(maybe good for racing) My da 100 has twice the power on low-mid than the 3w 150.I wonder what mod#walbro would rplace the tillitson?Every da I've seen came right out of the box and ran great.No tuning for hours and hours.
