I was checking my throttle cables on my 01 426 & after removing the plastic cover I found a small return spring hooked up to the top of the wheel when looking at the cables directly on the carb. I have also noticed a noise when I move the throttle with the engine off as the spring is contacting the cover. The throttle returns but very (in my opinion) very slowly. The cables are not frayed & I don't think this spring belongs there but it does look factory. The throttle end of the cables look fine but they do move when I open or close the throttle.
