Default Re: Stromberg WW throttle return spring

Which Holley 2bbl do you have? There is 500cfm #4412 carb and then there's the smaller the 350cfm version #7448. If you're running the smaller 350cfm version then it's fully understandable there are no performance gains over the stock WW carb. If it's the 500cfm carb then it has some serious issues
